Purple Imperial Topaz
Ouro Prieto, Minas Gerais, Brazil
Thumbnail, 2.2 x 1.0 x 0.8 cm
This really fat thumbnail crystal is an impressive thumbnail specimen because it has the depth/volume ratio to have the deepest color in this material, and it really does thus have more impact than others of its height. It is perfectly terminated with a complex stepped termination, frankly unusual. Weight is around 3.5 grams. This is, to me, one of the 2 or 3 most impressive fullsized thumbnails in the lot for overall showiness.
