Geological History

In a lion-infested, dry area of Africa, amongst the Taita Hills of Kenya lies the place where Tsavorite was discovered and first mined. The basement system of rocks within which Tsavorite forms has been dated at between 800 million years and 1.2 billion years old. Tsavorite formed sometime during this time due to a process called “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.

Millions of years later, as miners chiseled away at the mine face in the Wandani mining area they came across a “potato” or gem pocket. They chiseled it open and inside was a concentration of intense green gem quality Tsavorite. This was carefully clipped away from the host rock and collected into a “parcel” which was taken to Nairobi. Here, in the Lapigems offices they were identified as fine Tsavorite crystals using sophisticated gemological equipment. They were bought, sorted and then “knocked” (a process using fine gem tools) in order to remove heavily included sections. Once this process was complete, the now clean crystals were then examined and cut. Cutting is a long and highly skilled process and our master cutters have over 30 years of experience each.

This Tsavorite was one of the crystals purchased from this fine parcel and what you see before you today is several billion years old and a true gift of nature.
