Coquimbite

Item Description

Coquimbite is a fairly well known sulfate, but good crystallized specimens are few and far between. There are only a handful of localities that produce really nice Coquimbites, and a serious discovery of this minreal was made in 2009 at the Javier Mine in Peru that produced what are the finest examples of the species extant. This piece when backlit shows a strong/vibrant purple hue, despite the fact that it has a bit of iron-staining on the surface. The crystals are fairly well-formed for the material, and for the size of the specimen, this is a good representative piece of a mineral that few collectors have in their collections. The attached matrix is a nice touch to this attractive thumbnail sized specimen.
