TitleNative copper in calcite
DescriptionHere we see mostly native copper (dark brownish color) with calcite (white). The copper is tarnished, and so does not have a “coppery” color. It has altered to green malachite (a hydrated copper carbonate) in some places. Native copper is not very common, and generally is found only in small quantities. There are, however, a few places where it is abundant. Well crystallized specimens are especially uncommon, and are very much sought after. This sample is 14 cm across.
