There are scores of small Chalcopyrite crystals amid the quartz crystals on this specimen. They range in diameter from 1 mm or less up to 0.3" (0.8 cm), and have excellent disphenoidal form, though many of them are intergrown. Their color is an unusually deep gold that fades to an almost rusty orange in some areas, and they all have a dull metallic luster. They are accompanied by a few small but well-formed pyrite crystals that are easily discernable due to their pale golden color and much brighter luster. The quartz crystals that pervade the surface have the standard hexagonal prismatic form with six-sided pyramidal terminations. They are transparent, clear, and have an unusually dull, pearly-to-waxy luster. Their lengths range from about 2 mm to 0.5" (1.3 cm). The intense contrast between the whitish quartz crystals and the deep golden Chalcopyrite made me notice it immediately.
