<<< BACK TO LIST Chalcopyrite (fine Euhedral crystals) Commodore Mine, Creede, Mineral County Colorado, United States 5.5 x 4.1 CM (small cabinet/ large miniature) price: $360 An extraordinary, sharp and brilliant Chalcopyrite from the classic Creede district. Chalcopyrite is a delicate, brittle mineral that rarely survives without damage, it is quite rare to find really good crystal specimens. This is a very fine example with rich patina and form, individual crystals reach 2.2 CM and the overall condition is outstanding, no eye visible damage! Fine piece for the locality and for the specie.
