If you’re contemplating green gemstones, one rare but beautiful alternative to emerald is a Tsavorite garnet.
Tsavorite garnet is one of the most important varieties of grossularite garnet. It was first discovered in 1967 by Campbell Bridges, a Scottish geologist. Tsavorite was named after Tsavo National Park on the border between Kenya and Tanzania, where the stones were discovered.
Tsavorite garnets are about 200 times rarer than emeralds, and they are among the most expensive types of garnets because of their rarity.
These types of garnets also tend to be small in terms of carat size. The majority of stones are under one carat. Pieces over two carats are rare and therefore significantly more expensive than the smaller stones. The most preferred color is a pure, highly saturated green.
Unlike emeralds, inclusions are rare, so Tsavorite garnets don’t typically need to be treated or filled. They have a high refractive index which makes them especially brilliant. They are moderately hard, measuring 6.5 – 7.5 on the Mohs scale.
