Incredibly gemmy, lustrous and striated golden-amber sphalerite crystals to 1.3 cm along with metallic-yellow chalcopyrite crystals and one nicely hoppered galena crystal make for an excellent combination piece from the famous Commodore Mine in Creede, Colorado. The golden flashes from the gemmy sphalerite crystals are really striking. This is about the gemmiest Commodore Mine sphalerite that I have seen and the combo with the oither sulfides adds to the beauty. 4.2 x 4.2 x 1.8 cm
