Violarite

Sulfide mineral,thiospinel group,spinel structural group

Violarite (Fe 4) is a supergene sulfide mineral associated with the weathering of primary pentlandite minerals.

Violarite crystallises in the isometric system, with a hardness of 4.5 to 5.5 and a specific gravity of about 4, is dark violet grey to copper-red, often with verdigris and patina from associated copper and arsenic sulfides, and is typically in amorphous to massive infill of lower saprolite.

Violarite has a characteristic violet colour, hence the name from the Latin 'violaris' alluding to its colour especially when viewed in polished section under a microscope.
