Celebrating 50 Years of Tanzanite!

by Lapigems Gem Company 8. June 2017 22:38
This year the world celebrates 50 Years of Tanzanite.


This year the world celebrates 50 years of this exceptional gemstone. The Ultimate Blue Gem & One of the Worlds Rarest.



How befitting that such an exceptional gemstone should have such a dramatic story behind it…


The Legend…

Legend has it that the spectacular landscape below the towering heights of Mt. Kilimanjaro was set alight by lightning and the heat from this “magic fire” transformed the dull brown crystals on the surface into bright shards of violet/blue gems. The local Maasai tribesmen discovered these striking blue shards whilst walking through the smoke and ashes after the fire ebbed and have since believed that these magical stones will bring them an enriched life.

1000 Times Rarer Than Diamond –Tanzanite’s Rarity

Tanzanite formed 585 million years ago in a metamorphic event under Africa’s largest mountain, Mt. Kilimanjaro. Geological research has shown that Tanzanite’s geology is totally unique and only found within a very small area on the foothills of this spectacular mountain and the chances of it being discovered anywhere else is less than “one in a million”. This, combined with the likelihood of Tanzanite running out completely in the near future, all contributes to the stone’s appeal.



Tanzanite’s Discovery - 1967

Discovered in the foothills of Mt. Kilimanjaro in the Merelani Hills in Northern Tanzania, in 1967 by Manuel d’Souza. A tailor and part-time gold prospector living the area, found fragments of violet/blue crystals whilst walking and assumed they were Olivine (Peridot). After testing them, he realized they weren’t and concluded they were “Dumortierite” a blue non-gem mineral.

It was John Saul a Nairobi based geologist, who later contested this theory and sent samples to his father, Hyman Saul, vice president of Saks Fifth Avenue in New York to take to the Gemological Institute of America for correct identification. They identified the samples as a new gem of the variety, Zoisite never seen before.


Tanzanite’s Re-naming by Tiffany & Co. – 1968

It wasn’t until Henry B. Platt, great grandson to Louis Comfort Tiffany, President and Chairman of Tiffany & Co. who christened Blue Zoisite to “Tanzanite” after the country it was discovered and declared it to be “the most important gemstone discovery in 2000 years.” With powerful marketing from Tiffany & Co. over the next decade, Tanzanite became the ultimate blue gemstone.

Ranked the 2nd Most Popular Colored Gemstone - 2001

In 2001 sales of Tanzanite soared, exceeding all other colored gemstones except Sapphire and it was ranked the second most favorite colored gemstone. The stone's beauty and mystery endeared it to consumers and people flocked to purchase it. Everyone wanted to own a piece of this extraordinary gemstone and be a part of its history. Tanzanite's star was truly in the ascendant.


Named as the new Birthstone for December – 2002

In recognition of its popularity, Tanzanite is added to the industry's official birthstone list.  A true honor, as this was the first addition to the Birthstone list since 1912. It joined Zircon and Turquoise as December's Birthstone. 

As well as being named the birthstone for December, Tanzanite is regarded the gemstone to purchase for your 24th Wedding Anniversary


We are celebrating 50 years in the life of Tanzanite, there will not be another 50

This beautiful and very rare gem will soon have to be inherited to be owned.

The Vibrant World of Green - Inspired by Nature

by Lapigems Gem Company 2. March 2017 22:19


The Pantone Color Institute recently announced its color for 2017 as “Greenery” A vibrant green with yellow undertones. https://www.pantone.com/color-of-the-year-2017


Greenery symbolizes new beginnings and is said to “evoke the first few days of spring when nature’s greens revive, restore and renew.”  

In a release, Pantone Color Institute executive director, Leatrice Eisenman said: “Greenery bursts forth in 2017 to provide us with the hope we collectively yearn for amid a complex social and political landscape. Satisfying our growing desire to rejuvenate, revitalize, and unite, Greenery symbolizes the reconnection we seek with nature, one another, and a larger purpose."

Pantone calls Greenery “Nature’s neutral” a hue more prominently worn during spring and summer, but one they encourage people to wear as a statement color year round.

Already Seen on this Year’s Runways!

Leading fashion houses such as Gucci, Kenzo, Bagelencia, Michael Kors, Versace, Zac Posen, and Cynthia Rowley have already been using various shade of green in their collections.



“At New York Fashion Week, the designers were explaining how we live in this modern world where technology will always exist, but there’s this need to turn to design to go to the opposite side, to Nature” Pressman said.

Tsavorite - colors vary from a vivid, light to deep, rich emerald green color. It has a particularly amazing brilliance that cannot be compared with other green gemstones. The stone is becoming one of the trendiest garnets. This can be accredited to the fact that it is only found in the exclusively beautiful landscape, rich and varied wildlife found in Tsavo National Park along the Kenya and Tanzania border. 

Tourmaline – a truly fascinating stone. One of the only gemstones that exhibits the broadest spectrum of colors, occurring in various shades of virtually every hue, it can even be bi- or tri-colored. As there are so many different colors, different names have been given to the most popular, for example, Chrome for the intense green. We specialize in very fine, selected Tourmalines from Africa and being based at the source, we have the enviable opportunity to select out the very best rough as it is produced from the mines for our Private Collection. Our master cutters fashion them carefully to release their inner fire.

Being based just over the border from Ethiopia we are right at the main source and are able to select out the finest pieces.

Canary Yellow Sapphires & Canary Yellow Diamonds - The Wonderful World of Yellow

by Lapigems Gem Company 15. September 2016 01:30
Canary Yellow Sapphires are an excellent, more affordable substitute for that Canary Yellow Diamond you have been coveting but can't afford!


Canary Yellow Diamonds have made a big splash in the jewelry world in recent years. There have been numerous celebrity sightings wearing spectacular jewelry featuring Canary Yellow Diamonds.

In 2010, Kate Winslet lit up the red carpet at the Oscars wearing a $2.5 million necklace that was paired with Canary Diamond earrings worth $975,000.

Lucy Liu at the 2014 Emmy Awards wearing spectacular Canary Diamond earrings that weighed over 50 carats and a 13 carat Canary Diamond ring to match. Their total cost was $6 million.

Famous Canary Diamond Engagement Rings include:

“Canary Yellow” is not an official color grading term but it is widely used in the trade to describe the color of a stone. Only intense, pure yellow stones can be “Canary Yellow”.

Love Them, Can’t Afford Them!

Yes, we know. They are stunning, but Kate Winslet’s $3.5 million budget may be slightly over most people’s, but this doesn’t mean you can’t be bedecked in something just as beautiful – Canary Yellow Sapphires! Natural, fine, untreated Yellow Sapphire is just as captivating and way more affordable. Jenny McCarthy, for example, loves her Canary Yellow Sapphire engagement ring.

Got A Special Birthday Or Anniversary Coming Up?

Sapphire is the September Birthstone and the 5th & 45th Wedding Anniversary Stone and though traditionally blue, why not splash out and go for a yellow one instead!

Spinel - The New August Birthstone

by Lapigems Gem Company 27. July 2016 22:54


Recently added to the official list of Birthstones by the American Gem Trade Association (AGTA) and Jewelers of America and will now share the month of August with the stunning yellow/green gemstone Peridot. This is the third recent addition to the modern list since it was created in 1912.

“At certain moments in history, when there is a strong call from gem enthusiasts to expand the list of official birthstones, Jewelers of America believes in recognizing the importance of historically significant gemstones and giving gemstone lovers a choice that suits their preferences,”
said JA President and CEO David Bonaparte.


A favorite among dealers and collectors due to its wonderful brilliance and sparkle, hardness and wide range of stunning colors. Known mainly for its beautiful rich reds, Spinel can also be found in many other gorgeous pastel shades of purple and pink such as those discovered in Umba in Tanzania in the late 1990’s which are unique. Recently found is a striking hot pink tinged with orange from Burma. Wonderful shades of blue have also been discovered, for example Cobalt Spinel, found in Sri Lanka and Vietnam.

Like Garnet and Diamond, Spinel is singly refractive and has the same physical properties in all crystal directions, it has octahedron crystals. Spinel also has a similar structure to Ruby and is found in many of the same locations, leading to great confusion in gemstone history as they have often been confused. Ruby is aluminum oxide, while Spinel is magnesium aluminum oxide formed when impure limestone is altered by heat and pressure. Both red/ pink Spinel and Ruby get their reddish color from impurities of chromium.

The source of both gems is said to be Myanmar, Burma. The Myanmarans have always recognized Spinel as its own species, but beyond, Spinel was referred to as "Balas Ruby" for hundreds of years. It wasn’t until 1783 when Mineralogist Jean Baptiste Louis Rome de Lisle identified it as a different mineral.

In Burma they believe that because Spinel is so perfect, they refer to it as “Nat Thwe” or “polished by the spirits”. In Ancient times, some mines produced exceptionally large crystals, some were treasured by kings and emperors. Some of these “rubies” are now actually Spinels. Famous examples include:


 “The Black Prince’s Ruby”

 A 170 carat crimson red cabochon Spinel set into the cross pattee in the Imperial State Crown in the British Crown Jewels. The stone is one of the oldest parts of the crown Jewels. It first appeared in historical records of fourteenth-century Spain, and has been owned by a succession of Moorish and Spanish Kings before Edward, Prince of Wales, the “Black Prince”, received the stone in 1367 as payment for a battle victory.

The stone was not actually set into the Imperial State Crown until 1685 for the coronation of King James 2nd. Her Majesty Queen Elizabeth 2nd was coroneted in the Imperial State Crown and she wears it annually at the Opening of Parliament. The crown is currently on display in the Tower of London. 


  “The Timur Ruby”

An unfaceted, unpolished 361 carat red Spinel presented as a gift to Queen Victoria by The East India Company in 1851 and set into a necklace by Garrards in 1853 as part of the British Crown Jewels and named after the ruler Timur (or Tamerlane) the great tartar conqueror. Until 1851, it was regarded as the largest known “Ruby” in the world. It is one of the most historically significant jewels that the Queen actually owns and is currently ranked as second in size behind the 398.72 carat Spinel in the Imperial Russian Crown.



The necklace has never actually been worn by any British Royal. Nevertheless, it is one of their greatest heirlooms. This stone has a very interesting and complicated history, parts of it can actually be derived from the stone itself, for some of the owners inscribed their names and/or additional inscriptions on it. This too, is currently on display in the Tower of London.


The Imperial Crown of Russia

or Great Imperial Crown sports a stunning 398.72-carat red Spinel, believed to be the largest red Spinel in the world. It was worn by the Emperors of Russia until the abolition of the monarchy in 1917. It was commissioned by Catherine the Great in 1763 for her coronation and made by the court jeweler Ekart and Jérémie Pauzié using the Spinel from the historic stones of the Russian Diamond Collection. The Spinel was brought to Russia by Nicholas Spafary the Russian envoy to China from 1675 to 1678 and was last used at the coronation of Nicholas II. The crown is currently on display in the Moscow Kremlin Armory State Diamond Fund.


Other famous Spinels include


Samarian Spinel – at 500 carats, this Spinel in the Iranian Crown Jewels is thought to be the largest “fine” Spinel in the world.


Carew Spinel – an unfaceted 133.5 carat stone, inscribed with the names of the Mughal Emperors. Bequeathed to the Victoria & Albert Museum by Lady Carew in 1922.


Mogul Names Necklace – An imperial necklace set with 11 polished Spinel beads from the Pamir region weighing a total of 1,131.59 carats. Three of the beads are engraved with the Emperors names.



The Healing Properties of Spinel

Believed to protect its owner from all harm and soothe sadness, to stimulate strength, promote physical vitality and bring high energy. It is said that Spinel can aid in the speed of recovery from all illness and disease associated with movement. In the mental realm, it is used to help reduce forgetfulness.


Spinel is a celebratory gem for 22nd Wedding Anniversary.





Amethyst "The Essence of Purple"

by Lapigems Gem Company 4. February 2016 23:01

The February birthstone and celebratory gem for the 6th and 17th Wedding Anniversary.

Unfortunately it has become a gem that is often thought of as “old fashioned”, “dull”, “boring” and “common”. But, is actually a beautiful, vivid stone – “the essence of purple” that has captured our hearts for hundreds of years!

Fascinating facts

Amethyst is a variety of Quartz that is found in many locations around the world and forms as terminated crystals of all sizes in geodes, clusters and as long single terminations. Some geodes (hollow, crystal lined bubbles) are big enough for a person to stand in!

The name comes from the Greek méthystos ("intoxicated") a reference to the belief that the stone protected its owner from drunkenness.

Its purple coloring is usually caused by impurities of Iron or Manganese compounds. Amethyst is often routinely heated to bring out a deeper purple color.

Amethyst is found in Russia, Brazil, Uruguay, Madagascar, Zambia and parts of the United States.

Amethyst was as expensive as Emerald or Ruby until the 19th Century when large deposits of it were discovered in Brazil. Today it is the most valued of the Quartz family.

The healing and spiritual meanings of Amethyst

Amethyst crystals are exceptional for providing spiritual protection, inner strength and clarity of mind, making them a classic meditation tool.

Amethyst healing properties also include acting as a natural form of stress relief and attracts positive energy while ridding your body of any negative emotions, they are said to help strengthen the immune system and heal any imbalances that lie in the body.

They are said to be beneficial to your environment, working to purify any space of negative vibrations.

Colour Psychology – Purple





A little bit of history about Amethyst

• The Ancient Greeks wore Amethyst and made drinking vessels decorated in them to prevent themselves from being intoxicated.

• In the middles ages it was considered as a symbol of royalty and a “cardinal gem” and was used to decorate English regalia.

• Medieval European soldiers wore Amethyst amulets to protect them in battle.

• An Amethyst is the ninth stone in the breast plate of the high priest of Israel, and one of the ten stones upon which the names of the tribes of Israel were engraved.

• The ancient saint St. Valentine, the patron of love, wore an Amethyst ring carved with a cupid. Hence, why it is also the birthstone for February.

• Tibetans have always considered Amethyst to be sacred to the Buddha and make prayer beads from it.

Famous Amethysts

An Amethyst known as The Deli ‘Sapphire” is said to be cursed since it was looted from a temple in Kanpur, India, during the bloody Indian Mutiny of 1857. It is now in the collection of the Natural History Museum in London.

The Tiffany Amethyst. A 56 carat square cushion cut Amethyst, now in the collection of the Smithsonian Institution.

The Morris Amethyst Brooch – made most likely during the Edwardian period featuring a 96 carat heart shaped Amethyst. It was donated to the Smithsonian Institution by Mrs. M. Morris in 1973 and is now on display at the National Museum of Natural History.

Celebrating Sapphire – The September Birthstone

by Lapigems Gem Company 9. September 2015 03:04


It is September; and we are celebrating Sapphire! According to legend, Sapphire protects loved ones from envy and harm. Clergy would wear Sapphire to symbolize heaven, while the congregation felt the stone attracted blessings from heaven. Sapphire occurs in all the colors of the rainbow. We will however focus on Yellow Sapphire this month.

Yellow Sapphire is mined by local nomadic tribesmen in Garba Tula, North Eastern Kenya. It is a very dry, wild part of the country with some spectacular scenery as seen in the photo of the area below.

The mines in the area are popularly known for having a dark blue inky material. They produce pockets of intense yellow sapphires occasionally. The yellow stones also have a blue color zoning and usually produce very unique bi-color gemstones. Sapphires in this area are some of the finest natural canary yellow and yellow-blue bi-color found in the world.

Kenyan Yellow Sapphire stands out because they are untreated and entirely natural. They are naturally clean stones with a wonderful sharp yellow. Being untreated commands a premium in the Sapphire market.

The amazing thing about Kenyan Yellow Sapphire is that it is not treated. It is only cut!

How to Identify Yellow Sapphire

Before purchasing a Yellow Sapphire, it is important to ensure that the stone is natural and relatively flawless. Below are some of tips one can use to identify fake Yellow Sapphire.

(i) Most fake Yellow Sapphires are usually made from glass. To ensure the Yellow Sapphire is legit, compare it to yellow glass. At a glance, they look very similar, but in comparison with one another, one notices that yellow glass happens to be too big and saturated to be genuine.

(ii) High quality Yellow Sapphires seldom have inclusions that are visible without high magnification, whereas fake sapphires usually contain small bubbles inside.

(iii) Sapphire ranks at 9.0 on the Moh’s hardness scale. Glass, however, ranks between 5.5 and 6.0. This automatically means, glass is much more easily scratchable as compared to Yellow Sapphire, or any Sapphire for that matter. A glass imitation of Yellow Sapphire is also more likely to have scratches on the surface.

(iv) Glass is cut much more easily as compared to Sapphire since it is not as hard. Therefore, yellow glass stones are usually cut very simply and have smooth rounded edges. Yellow Sapphires’ cuts are complex, sharp and crisp.

How to Identify Synthetics

(i) Natural Yellow Sapphires can be cut into almost any style. However, if a stone is larger than a carat, it will most likely be cut into a cushion or oval mixed cut. Jewelers usually cut synthetic sapphires into round or emerald shapes.

(ii) Synthetic stones usually have an “X” cut, also referred to as a “Scissors Cut”, on the facets of a stone.

(iii) Once in a while, facets of a synthetic stone will not come out as crisp and sharp as those of a natural Yellow Sapphire would. This makes it look very similar to grooves seen on a vinyl record, though only visible under 10x loupe magnification.

(iv) A good synthetic stone may have flaws that are visible under 10x-30x magnification. A lower magnification usually shows the curved banding in synthetic sapphires. This gets even more accurate if the person doing the examining places a piece of translucent glass between the light source and the stone. 30x magnification and above shows gas bubbles and masses of un-melted powder.

How to Identify other Tricks

(i) Yellow Sapphire will occasionally have inclusions in the stone which may develop into small holes when a gem cutter slices into one of them. However, untrustworthy jewelers may fill the hole with glass or borax weight with the aim off adding weight, or making the stone appear to have higher quality. To ensure the stone is of good quality, examine it by shining a light on it. If it has patches of unevenness, then chances are that it may have fillings.

(ii) Genuine Yellow Sapphire is pure yellow. Other imitations that are less precious usually have different hues. For instance, Golden Topaz contains strong traces of the color orange, whereas Citrine has a slight tint of green. Yellow Tourmaline on the other hand has brighter, lemon-like tone.

(iii) If doubtful, it is always advisable to buy loose stones or those that have settings that allow you to look at the bottom. Closed settings such as bezel mounting are often used to hide flaws. Claw, tension and channel settings are okay.

Handmade Jewelry vs. Casting

by Lapigems Gem Company 12. August 2015 21:10


Most jewelry in the world today is mass-produced using a process called casting. Most people don’t know the difference between the ages-old method of hand making fine jewelry and the more ubiquitous mass production of today. This article takes a look at the two processes.



Most jewelry purchased today in mall jewelers and jeweler chain stores is mass produced. Thousands of the same design are created using a process called casting and then standardized size gemstones are dropped into them. Most of this jewelry is made in the Far East; places like Hong Kong, China and Thailand being the centers of jewelry production. Casting involves a design being carved by a CAD machine into a wax model containing multiple versions of the same designs. A special plaster is then cast around the wax model and finally, once the plaster has set, the wax is melted out, leaving a cavity insode the plaster. Molten gold is then poured into this cavity and once cooled, the plaster mold is broken and the individual jewelry pieces are clipped off the “tree”, polished and the standardized gemstones set.


The image above gives an illustration of this process. The middle image shows a “casting tree” removed from the plaster mold, with numerous rings cast. These are duly clipped off. The image on the right shows the CAD produced wax models.

This is a very efficient method of producing jewelry for catalogs and volume business models. However, there is not much emotion or empathy connected with the process. It is a method that has been necessitated by the rapid growth of the jewelry industry worldwide as greater affluence has created greater demand. Casting is a relatively quick method of making pieces that are identical. It is economical especially when the same mold is used in production of many pieces. This method of production usually means that individuality and uniqueness are lost. Quality is forfeited for quantity, ease and speed. Use of wax also dulls the design’s precision, and the process introduces air bubbles and contaminants into the metal. Numerous cleanings and filing to remove roughness coupled with this, results in a piece of jewelry that is fragile and has minimal detail.

Hand Made Fine Jewelry

By contrast, most fine jewelry is made individually. It is a process that requires a very high level of craftsmanship. Jewelry that is handmade is usually directly crafted from metal without the use of any mold, wax or additions. A single piece of jewelry would be worked on for weeks at a time by craftsmen with skill and a level of passion that was passed down for many generations throughout history. Generally the process starts with choosing a fine gem for its rarity and quality. Then a design is created around the gemstone.

A piece of jewelry that is handmade is naturally stronger since the metal has been hardened by the process of bending, rolling, shaping and hammering. All aspects of the piece have to be finished to a high standard. The setting that holds a gemstone is usually individually crafted and the claws are harder and less likely to be porous, common in a cast. The video below illustrates the ancient , highly skilled art of handmaking fine jewelry, specifically our own line, designed and made by Sheelagh Zagoritis.



It is unfortunate then, that the vast majority of jewelry in the world today is produced by casting since it tends not to live to the heirloom stage. Jewelry that is handmade is a product of time, accumulated knowledge, and patience making each piece valuable and irreplaceable.

A look into the May Birthstone - Emerald

Emerald, the May birthstone, are a symbol of rebirth. The stone is believed to give the wearer a heightened sixth sense and extrasensory perception. The term ‘Emerald’ comes from the Greek 'smaragdos' via the Old French 'esmeralde', which basically means 'Green Gemstone'. Emeralds range in color, from bluish-green to yellowish-green. They are also very popular and costly.

In ancient Rome, Emerald green was the represented of Venus, the goddess of beauty and love. It has also been the color of beauty and constant love for centuries. Many cultures and religions still value the color; for instance, in Islam Green is the holy color. In the Catholic Church green is regarded as the most natural and elemental of the liturgical colors. Many Arab League states have the color green in their flags to signify the unity of their faith.

Emeralds clarity is graded using the naked eye, unlike diamonds, whose apparent clarity must be evaluated using a 10x magnification. The stone tends to have numerous inclusions and surface breaking fissures, known as ‘Jardin’ (a French term meaning ‘garden’), thus they are usually treated due to their mossy appearance. However, there are innumerable synthetics and imitations. It is therefore advisable to buy Emerald from a trusted specialist. Reputable gemological institutes have modern techniques to distinguish between natural and synthetic emeralds.

Most of the world’s emeralds are mined in Colombia, Brazil, Afghanistan, and Zambia. However, Emeralds are believed to have been mined in Egypt since 1500 BC. Today, Colombia produces over 50% of the world’s Emerald. Rare 'trapiche' Emeralds found in Colombia, distinguished by a six-pointed radial pattern consisting of ray-like spokes of dark carbon impurities. Zambia is responsible for 20% of Emerald production worldwide. Other countries that produce Emeralds include Australia, Austria, Bulgaria, Cambodia, Canada, China,Ethiopia, France, Germany,India, Italy, Kazakhstan, Madagascar, Mozambique, Namibia, Nigeria, Norway, Pakistan, Russia, Somalia, South Africa, Spain, Switzerland, Tanzania, United States, and Zimbabwe.

Fun fact, Emerald is the traditional gift for the 55th wedding anniversary. Its iconic green color is closely linked to spring and rebirth making it a perfect stone for the month of May!



Aquamarine – The Birthstone for March

by Lapigems Gem Company 5. March 2015 22:22


As you would expect from a gemstone whose name means sea water, Aquamarine is reminiscent of the cool blue waters of the Mediterranean Sea and is the official March birthstone. It is a member of the Beryl family. Unlike the Emerald, also a beryl crystal, which is usually heavily included or flawed, Aquamarine tends to form more commonly in spectacular crystals that are very clean by comparison. It forms some of the most stunning mineral masterpieces.

African Aquamarines

Recently, deposits of fine Aquamarine have been discovered in Africa. Most of these sources are mined by intrepid artisanal miners. This video tells the story of one such miner in Kenya.

The historical source of aquamarine in Africa was Madagascar. In the 1980’s, Zambia surprised the world with aquamarine that was rated 9.5 on a scale of one to ten. Mozambique followed in the mid – 90’s and was later joined by Nigeria in producing the enviable rough. This established Africa as a leader in quality and quantity of excellent Aquamarine that were comparable to the Brazilian deposits that were famous in the 1950s. More recently, there have been discoveries of various deposits from the African countries of Tanzania and Kenya. The map below shows the main deposits of Aquamarine in Africa.


Aquamarine, being a Beryl is closely related to Emerald in the gem kingdom. Most of the East African Aquamarines formed during the Panafrican orogeny 500-600 million years ago. As such, they are some the oldest gemstones on the planet. During that period, there was neither flora nor fauna on earth. During the Panafrican orogeny, several continents and microcontinents amalgamated to create a super continent called Gondwana. The collision of several continents caused the Mozambique belt to form. This famous geological formation is a zone of tectonically and thermally highly stressed metamorphic and magmatic rocks, which once was a huge mountain range reaching from Arabia through East Africa to Antarctica. Most gemstones of East Africa were formed by tectonic and magmatic activity during the formation of the Mozambique belt.

Aquamarine are found in large veins or dykes in this belt, consisting mainly of quartz, feldspar and mica – these are called pegmatites. The pegmatites formed from residual fluids (water and gases). By slowly cooling down rock forming minerals, e.g. quartz, feldspar and mica crystallised in the large magma chambers. What stayed behind formed a residual melt, which became more and more enriched in everything that did not fit in the normal rock forming minerals. This usually is water, gases and rare elements such as lithium, beryllium, boron, caesium, and fluorine. 


When the residual melt finally cooled down too, hydrothermal fluids exsolved and their increasing pressure broke the surrounding rock. The freshly formed cracks were then filled with quartz, feldspar, mica, and occasionally the rarer Aquamarine, forming a pegmatite vein.  

Aquamarine Lore

Legend has it that Aquamarine is the treasure of Mermaids possessing the power to preserve sailors at sea. This wonderful stone is also highly regarded in the metaphysical world. It is believed to have a powerfully soothing influence on relationships, particularly on married couples, believed to ensure a long and happy marriage. This is why it is considered such a perfect gift on a special Anniversary. 



Tsavorite – The World’s Rarest Garnet

by Lapigems Gem Company 13. January 2015 22:54

 This month we focus on Tsavorite; a relatively new gemstone in terms of market exposure, but with an extremely old geological history. The rocks in which  Tsavorite formed were first laid down over 2 billion years ago, thus making it older than Mt.Kilimanjaro, Africa’s highest mountain.

 The beautiful garnets’ home is the East African bush-land along the Kenya-Tanzania border in an area of barren, lion infested, and raw wilderness.  This  region has a history of volcanic activity and due to the volatile geological conditions under which it forms.

 Tsavorite was discovered by British geologist Campbell R. Bridges in 1967 in Tanzania and, about three years later, in Kenya. It was named by Harry Platt  of Tiffany & Co (New York) after the Tsavo game reserve in Kenya.  Indeed to this day, even though Tsavorites are found in other locations including  Tanzania, the very finest Tsavorite with the purest green hues are still only found in the Tsavo District of Kenya.

 Tsavorite is only found in relatively small sizes. Stones over 2.5 carats are considered very rare and valuable. The Smithsonian Gem Collection’s prize  piece is just 7 carats. The largest, cleanest Tsavorite on record is a 325.14-carat top-color beauty found near the Block B Tanzanite mines near Arusha,  Tanzania. It valued at over $2 million.

 Out of the two green varieties of garnets, i.e. Tsavorite and Emerald; Tsavorite is arguably the more important. Tsavorite brings greater competition  especially since it is less included, rarely treated and is more durable.  Emerald on the other hand is routinely oiled and glass filled.

 Tsavorite has earned its place as one of the world’s finest colored gemstones. Its high refractive index and dispersion levels translate into wonderful  brilliance; its durability and purity of its hues have attracted collectors and jewelry lovers alike. The romance of its origins and the fact that it formed even  before dinosaurs trod the earth make it a unique and exciting gemstone.


Tanzanite - The Birthstone for December

by Lapigems Gem Company 4. December 2014 20:18


Tanzanite has become very popular despite its recent discovery - so much so that it joined the league of turquoise and zircon as the December birthstone in 2002. This was no mean feat since the list had not been changed since 1912. Tanzanite was thus the first gem to be added to the birthstone list in 100 years.

Tanzanite is said to have been stumbled upon in 1967 by a Maasai tribesman who shared the crystal he had discovered with a prospector by the name of Manuel de Souza. No one knew what the stone really was and hence first speculated to be an unusually vivid and richly colored sapphire. However, it was soon discovered that the stone was more intricate and its colors more vibrant than the latter.

The stone was christened Tanzanite after its country of origin, Tanzania, in 1968 by Harry Platt, president of Tiffany and Co. who described it as “the most beautiful stone to be discovered in 2000 years.”

Tanzanite was categorized after the sapphire as the second favorite colored gemstone in the USA in 2001. While people initially bought it as a substitute for the sapphire since it was cheaper, its demand has skyrocketed in recent years as people began to value it more for its own sparkle, beauty, extreme rarity and the magic of its origins. 

Tanzanite is seen as the ultimate birthstone that represents new life. This comes from the affinity of the Maasai community with the color blue which they regard as healing, sacred and representing new life. It is therefore the perfect gift for new beginnings or celebration of a new life. If you were fortunate enough to be born in December you are one of the lucky few with this magnificent gemstone as your birthstone.

Focus on Aquamarine – One of the world’s Favorite Gemstones

by Lapigems Gem Company 3. November 2014 21:05
A look at Aquamarine as one of the world's favorite gemstones, with a video on Aquamarine mining.

The name ‘Aquamarine’ is derived from Latin; Aqua meaning ‘water’ and Mare meaning ‘sea’. The fascinating stone can be found in various blue tones, ranging from sky blue to a deep sea blue. It can also be found in a greenish blue tone. To determine a more valuable aquamarine, the secret is to check for a more intense and purer blue color.

Recently, some of the world's finest Aquamarine was discovered in nearby Mozambique. These stones rival the colors of the famous Santa Maria Aquamarine from Brazil, long recognized as the pinnacle of Aquamarine color. These stunning Aquas from Mozambique have been named Santa Maria Afrique after their Brazilian counterparts.  

Kenya and Tanzania also produce some beautiful Aquamarine; generally not the depth of color of the Brazilian or Mozambiquean stones but a stunning blue nonetheless with attractive hints of green. Some recently cut pieces can be seen here.

Lapigems Gem Company made a short video showing Artisanal Mining in Kenya. 

According to legend, the King of the Sea – Neptune, gave mermaids Aquamarines as gifts, thus bringing love to all who owned it. Another myth maintains that Aquamarine originated in the mermaids’ treasure chest and that is why it is considered the sailors’ good luck charm, guaranteeing them a safe voyage. Indeed, the stunning light blues and blue-greens of Aquamarine are strongly reminiscent of the ocean. These lovely colors tend to arouse a variety of emotions such as harmony, trust, sympathy and friendship. 

The precious stone was for a very long time thought to have a peaceful influence on married couples. Old traditions state that wearing aquamarine promises a happy marriage. It is also said that the precious gem brings joy and wealth to any woman who wears it. So next time you are thinking of a good anniversary gift, think Aquamarine!

Tourmaline Birthstone for October

by Lapigems Gem Company 30. September 2014 00:53
Tourmaline, the birthstone for October.


This month we are celebrating Tourmaline, the October Birthstone.Egyptian legend maintains that during its formation, Tourmaline passed over a rainbow as it made its journey from the Earth’s center which led to it assuming the seven colors of the rainbow. Indeed, Tourmalines are mined in a vast array of colors; the widest range of colors of any gemstone in the gem kingdom with virtually every color represented; even bi-colors and tri-colors.

“Tourmaline” is a term derived from the Singhalese words 'tura mali' meaning 'a stone with mixed colors'. Being dichotic, tourmaline has the ability to subtly shift its color depending on the light source as it changes from natural to artificial. Its diversity suits all moods, which is possibly why in metaphysics it is regarded as the gem crystal of Love & Friendship.

Tourmaline has many remarkable qualities but one of the most interesting physical attributes of the gem type is that it has the ability to become magnetic under certain conditions, namely under heat or pressure. When heat is applied to Tourmaline it becomes it to be magnetic, a phenomenon known scientifically as Pryoelectric. Similarly, applying pressure to it achieves the same effect (Piezoelectric).

In the gem kingdom, stones which possess a modicum of multicoloring are revered for their beauty and rarity. Tourmaline is one of the most versatile gemstone in this regard and ‘Watermelon Tourmaline’ is much sought after by collectors. These beautiful stones show both red and green colors (this could be a red center and a green surrounding, or a green center with a red surrounding). As a gem, the Watermelon Tourmaline is usually green from one end turning red on the other.

Tourmaline producers include Brazil, Pakistan, Russia, Burma, Sri Lanka and the USA. In Africa, the main producers are Congo, Madagascar, Namibia, Mozambique, Tanzania, Nigeria, Malawi and most recently Kenya. If you were born in October you are fortunate indeed to have such a stunning and versatile gemstone as your birthstone. Enjoy!

"The Heart of the Ocean" in the acclaimed movie Titanic, is another beautiful stone that is rumored to have been a Tanzanite. The blockbuster movie of 1997 revolved around the gem. The wonderful stone was set into a spectacular necklace. In one of the scenes, the lead character, Rose (Kate Winslet) requested Jack (Leonardo Dicaprio) to paint her whilst wearing only the gem. Certainly a unique way of promoting Tanzanite still unmatched!

In the movie, the Heart of the Ocean was depicted as a blue Diamond. However, in reality, blue diamonds do not possess such a deep blue saturation and the stone was actually a 28 carat heart shaped Tanzanite almost identical to this superb piece we have recently cut.

Tanzanite Prices - A Brief Analysis

by Lapigems Gem Company 6. March 2013 21:28
A brief analysis of Tanzanite prices through history and forecast for 2013 and beyond.


When Tanzanite was first discovered in the late 1960’s it was controlled by Tiffany & Company who gave it its name and were the first true marketers of the gemstone. Prices were high as Tiffany commanded a monopoly and supply out of the fledgling mines was low and sporadic. This continued through to the late 1980’s. Although Tiffany no longer controlled the market, the sporadic and unreliable supply from the mines kept prices high as demand increased with consumers in the US and other markets began to learn about and appreciate this wonderful gem. Tanzania, at that time, was a communist/socialist country under president Julius Nyerere and as such all mineral wealth officially belonged to the state. This led to lack of investment in the mining of the stone and very shaky production.

In the late 1990’s and early 2000’s as Tanzania adopted a capitalist economy, production stabilized and rose leading to a drop in prices further compounded in 2001 when the stone was implicated as a funding source to Al Qaeda in the aftermath of the 9/11 tragedy. Large retailers like Zales announced they were no longer going to sell Tanzanite and others followed suit leading to a catastrophic decline in prices. Fortunately this state of affairs did not last long as a full State Department / CIA report released in early 2002 cleared the industry of any links to Al Qaeda and Tanzanite rose again.



From 2002 to 2007 prices surged. From lows of $200 per carat for medium to medium/fine goods they rose to the heady heights of $600+ per carat before dropping back by 20-30% in the ravages of the recession in 2008/2009. The recession did not affect the prices of the very finest grades but medium/fine material and lower grades were severely affected. The finest grades were bolstered by ongoing demand from the relatively unaffected highest income brackets in the developed markets coupled with extremely low supply due to their rarity. Lower grades by contrast, lost up to 50% of their price value through 2009.

Through 2010 into 2013 prices have stabilized and returned to their pre recession levels and prices for the very finest stones are edging upwards again. China’s recent foray into the market and growing demand for Tanzanite in that country is another wild card that could affect the price trajectory in coming years. A lot will depend on the recovery of the largest market, the US and the buying power of the middle class consumer there. This will be the propeller for Tanzanite sales in the medium to medium/fine grades. The finest grades will likely see continued price inflation through prevailing low supply due to their rarity and high demand from high income brackets in the US and China markets in line with that of other gems such as ruby and emerald which have seen record prices reached for fine select stones at auction in 2012.

Our view on this is backed up by a recent article in National Jeweler which talks about how the impact of the rise of the Chinese and other emerging markets is affecting colored stone prices, Tanzanite being one of the main stones affected. Our view remains that the more ubiquitous qualities of Tanzanite, the medium and medium/fine grade colors will always be more susceptible to the vagaries of the market but the very finest stones will always hold their value and experience steady price inflation due to their rarity and burgeoning demand.

Tanzanite Heating - The Facts

by Lapigems Gem Company 17. January 2013 04:07
Tanzanite Heating. Why Tanzanite is heated and how it is heated.

Article by Antony Zagoritis (Graduate Gemologist, GIA)

Tanzanite, the blue variety of the mineral Zoisite, is a trichroic gemstone. In layman’s terms this means that it displays 3 different colors on 3 different axes/directions. In the rough state, when Tanzanite is mined, its appearance is largely of a brownish, treacle color. This is due to the dominance of the reddish/brown axis. The photograph below shows some Tanzanite before heating.


The blues and violets that Tanzanite is so well known for do not emerge until the stone is heated. This process is usually done in a gemological oven, at between 400 and 600 degrees centigrade. The heating process removes the brown / burgundy axis, leaving just the blue and violet axes. The heating process serves to render Tanzanite dichroic and permanently changes its original trichroic characteristics.

The photo below shows the same stones after heating.



The Science behind it

In scientific terms, color in Tanzanite is largely caused by the presence of Vanadium. Trace concentrations of vanadium within Tanzanite's crystals structure causes its unique color. It is believed that the Vanadium originates principally from the derived graphite within the deposit. Tanzanite's color largely relies on the Titanium and Vanadium ratio within its crystal structure. The heating of tanzanite results in a valence exchange reaction (redox reaction) Ti 3+ + V 4+ → Ti 4+ + V 3+ which causes an increase in the violet and blue color and renders the titanium colorless.

All Tanzanite is heated. Some pieces are partially heated in the ground and are mined already with some blue but these are generally heated anyway to remove any residual brown. The process is universal to the gemstone and in no way does it affect the value of the stone. Without heating, Tanzanite would be brown and the beautiful blues that are so loved would not be in existence. In fact, legend of the discovery of the stone back in the 1960’s dictates that the Maasai warriors who found it, did so after a large bushfire swept the area. The fire burnt all the foliage and undergrowth back revealing some Tanzanites on the surface and also heated them making them a sparkling blue and suddenly eyecatching. Without the fire, Tanzanite may never have been discovered as the Maasai may not have noticed them in their brownish shades against the bare, burnt earth.

Is Heating Considered an Enhancement in the Trade?

Unlike with other gemstones like Sapphires or Rubies, where heating at extremely high temperatures is used as a way of altering the actual grade of a gemstone, the heating process in no way enhances a Tanzanite’s color saturation levels it simply removes the red/brown axis leaving the blue/violet. A medium grade Tanzanite will appear lightish brown before heating and a medium pale blue/violet after heating. A top grade piece will be a deeply saturated brown before heating and a deep blue/violet after heating. Hence the process is not an enhancement, as it is with some gemstones such as Corundum..
