Tsavorites have been discovered in vary few places around the world. They are mainly mined in Tanzania (the Lemshuko tsavorite mine) and Kenya. Tsavorites are also found in Madagascar but in smaller sizes and quantities. Tsavorite is not only rare but even more so in bigger sizes. It is generally estimated that only 1% of all tsavorites are above 3 cts (after cutting). Tsavorites are formed under specific conditions; the important heat and pressure which formed tsavorite shattered most of the stones. Tsavorites, if not shattered, are expected to be included. A clean 3 cts tsavorite of the right color is thus not easy to come accross.
Swala Gem Traders has bought and mined a few very large pieces (some of which are pictured below). If a 3 cts tsavorite is considered large, how about a 20 cts gem? and a 50 cts? how about a 100 cts + tsavorite?
These huge pieces don’t seem to make much sense, do they? It seems as if they would have to defy nature to be so big and clean.
