One of the newest and rarest discoveries in the gem world. As a mineral Hibonite is know from various locales (Malagasy specimens are black and opaque!), but no one seems to have expected the occurrence of gem crystals of this species. These are found in Mogok, but there has an exceptionally small amount of higher quality material found. This outstanding find was written up in GIA's Gems & Gemology in early 2012.
The color is an attractive medium
brown and the stone is remarkably clean for this species. Considering the
rarity, it is a very impressive stone in terms of size and appearance. A
laboratory certificate from Gem and Jewelry Institute of Thailand accompanies
piece. By sheer census numbers, the rarest species we have handled and one of
the few changes to obtain an example.
