Description
A terminated and reasonably gemmy topaz crystal from Madagascar.Topaz is not very common in Madagascar-- for all the gem materials found on the island, good topaz is remarkably difficult to find. Although not an absolute measure of rarity, Mindat only has 6 photographs of Malagasy topaz-- that alone attests to the scarcity of the mineral there.This is a very well formed crystal, and particularly transparent compared to the couple others I have seen.
