What some of our past clients said :

"Just thought I would share this story with you. my wife and I recently upgraded her engagement diamond to a 2 carat stone. we attempted to set the tanzanite I purchased from you using the same chain jewelry store we bought the diamond from. their jeweler said he would not work with the tanzanite because if anything were to happen to it in the setting process, the store would not be able to replace such a high quality stone. Every employee in the store came over to admire the tanzanite and each stated they had never seen such a high quality tanzanite. I am just glad my wife was there to hear them all gushing over the stone ."

Specialists in the Rarest Grades of Tanzanite

Not all Tanzanite is created equal. If you are looking for a very special Tanzanite that is out of the ordinary, that is extremely rare and of a pedigree that very few people will ever own or even see, then we are the specialists

Out of the Ordinary and Extremely Rare

There exists, in Tanzanite mining lore, a rare class of stone the miners call “Nadra”, meaning “The Rarest” in their native Swahili. A miner may find only a handful of these coveted crystals in a year. These Tanzanites have a color not normally seen in the main market. Their color is beyond the normal grading scales.

Just as certain gem types have their pinnacles - blue sapphire from Kashmir for example has a color saturation and tone mix that makes it unique and highly coveted, not only for its rarity but superior beauty. This is how these particular stones are regarded

Lapigems Investment Grade Collection

Our Tanzanites are cherry picked from the mouth of the mine by a GIA Gemologist, chosen out of literally thousands of carats of Tanzanite production. This gives our Investment Grade Collection a pedigree that very few people will ever own or even see. If you are looking for the highest grade in Tanzanite, the very top 1%, we are the specialists.

How Rare is Tanzanite

Tanzanite is one of the world's rarest gems. There is only 1 source in the world for Tanzanite, which almost mined out and there is growing speculation that Tanzanite is about to become extinct. The top quality Tanzanite, traditionally constituting only 1% of all production, are now becoming exceptionally scarce. Henry Platt, ex president and chairman of Tiffany & Company sums up the essence of the stone with his comment "Tanzanite is the most important gemstone discovery in over 2000 years." Tanzanite's unique position in the gem kingdom means that once it is mined out, those who own top grade stones will be in an enviable position. Tanzanite will be the quintessential heirloom of our generation.
