15dm006 ((PYRITE, CHALCOPYRITE, QUARTZ)), $5 MINIMUM BID, Huaron, Peru, 7 x 5 x 3.5 cm, Cabinet | |
Here is a fine undamaged specimen from Peru. It has very lustrous Pyrite crystals, large dark black Chalcopyrite crystals, with minor Sphalerite and Quartz. The Chalcopyrite faces also have some small acicular crystals looking like small Stibnite crystals but I do not know what they are. ex Dennis McMurdie collection, a local Utah teacher and mineral collector. |
