Covellite

Sulfide mineral

Covellite (also known as covelline) is a rare copper sulfide mineral This indigo blue mineral is commonly a secondary mineral in limited abundance and although it is not an important ore of copper itself, it is well known to mineral collectors.

The mineral is generally found in zones of secondary enrichment (supergene ) of copper sulfide deposits. Commonly found as coatings on chalcocite , bornite, and other sulfides, it often occurs as pseudomorphic replacements of other minerals. The first records are from Mount Vesuvius Research of its unique properties has only surged in past decade yet promising results suggest may be used widescale in certain specific applications in the future.
