Tsavorite (a name Tiffany marketers derived from Kenya’s famous Tsavo Park in 1974) is found only in East Africa. Tsavorites over 3 carats are exceedingly rare.
To get at this tsavorite, especially that embedded in the hills, takes expensive earth-removal equipment run by currently ultra-expensive diesel fuel. All this requires lots of venture capital, a commodity that doesn’t flow as readily into Africa nowadays as it did in the 1970’s.
It’s cheaper, harder and more brilliant than emerald, plus it’s untreated. That makes it a far better gem to pair up with diamonds.
No matter what happens with jewelry manufacturers, however, tsavorite is likely to stay a favorite of collectors and investors. For one thing, it boasts almost non-stop price appreciation since the early 1970’s
When buying tsavorite, dealers say to expect eye-clean stones. With regard to color, jewelers should look for a green that is reminiscent of that found in imperial jade.
