Peacock Ore
Chalcopyrite is sometimes found as crystals. It fractures like glass and is brittle and is only 3.5 to 4.0 on the hardness scale. If you scratch it on a white porcelain plate the streak of powder left behind is dark green.
Sometimes copper pyrite is richer in copper and then it tarnishes to red, brown, purple of green, and is far more iridescent and is the usual source of the peacock appearance. Then it is called Bornite. The difference:
Chalcopyrite is CUFES2 and bornite is CU5FES4.
