Thumbnail, 2.5 x 0.9 x 0.9 cm
Rweko, Nkasi District, Rukwa Region, Tanzania
One of the gemmiest Zircons I have seen from Tanzania, of competition level thumbnail gem crystal size. It has a beautiful orange/red hue, with sharp pyramidal modifications on the termination. The faces are all sharp except only a thin contact on back of the termination and one ding on a back edge; and when the piece is backlit the color really shines through. A fine gemmy and colorful crystal that would yield a good sized gemstone, and is a hell of a display thumbnail for the species. Mined in late 2011
