An unusual etched topaz crystal from the same find that produced the blue bicolored specimen also on this update. There is a bit of reddish brown African dirt under the surface of the crystal that gives it the rusty color-- I've made it cheaper because of that, though the form is excellent.
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.
With that said, I've never seen another find of topaz like this from the country.
