Geological History

Tsavorite is an ancient gemstone. It was formed before even the dinosaurs walked the earth and was already old when the mighty Mt. Kilimanjaro, Africa’s highest mountain was in its infancy. When you consider that this particular piece of nature is as old as it is, you begin to understand the incredible history behind it.

It began life a billion years ago in what is now a very dry and dusty part of Africa dotted with thorn and acacia trees. This area is called Taita and is adjacent to the Tsavo wild game reserve, one of Africa’s largest from which it derives its name. The scientific process by which it formed is known as “metamorphism”. As magma pushed its way up through the existing rock the contact between the invading magma and the older rock caused a change to occur. The intense heat (as high as, and exceeding 750 degrees centigrade (about 1,530 degrees Fahrenheit) made the nearby minerals recrystallize into minerals stable at the higher temperature. This Tsavorite was one of these.

The prevailing conditions of pressure and heat remained constant through the ages and this what made it possible for Tsavorite to form. As the rock folded, many of the crystals were crushed, as is the case with most Tsavorite due to the very volatile geological conditions particular to its formation. This particular piece remained a fairly large size which is unusual – most Tsavorite crystals are crushed down to chippings. They generally form in gneisses or “potatoes” as they are known amongst the mining community. These are balls of hollow host rock with Tsavorite crystals forming in the hollow space. This crystal was most likely one of the lucky ones that escaped the crushing action of the folding rock in an intact potato.

There are a number of locations along the Tsavorite belt where this beautiful gemstone is mined, but there is only one area which produces a very rare colour of Tsavorite containing a hint of blue. This is considered the ultimate colour in Tsavorite and a very few stones are mined every year from this deposit. The cause of the superior colour is a touch of Chromium in the ground along with Tsavorite’s normal colouring agent – Vanadium. This place is called Kuranze and Tsavorites mined from here are much coveted for their quality.

This particular stone was mined in Kuranze and is a very fine piece. It was carefully extracted from its home of aeons by miners using delicate chiseling tools. It made its way through a network of miners and brokers who ferried it to Nairobi. The brokers brought it to their assigned office at Lapigems Gem Company where it was cut into what you see today. This is a very special and very rare piece of nature.
