Sphalerite, Chalcopyrite
Commodore Mine, Amethyst Vein, Creede District, Mineral Co., Colorado, USA
Small Cabinet, 5.5 x 3.3 x 1.7 cm
A SUPERB and AESTHETIC combination plate from the famous Commodore Mine at Creede, Colorado. Three, sharp, lustrous and brassy chalcopyrite crystals rest clustered on a matrix of very GEMMY and LUSTROUS, olive-green sphalerite crystals. A small lot of these was offered at Tucson a few years ago and they quickly disappeared.
