Roselite is a beautiful, but extremely rare hydrated calcium cobalt arsenate mineral - its stunning cerise pink colour being imparted by the presence of cobalt in it structure. It was first described during the early 19th century from Rappold mine in Saxony, Germany, from where the best crystals were known for over one and a half centuries until finds in Morocco, later in the 20th century, rewrote the quality guide. Aghbar mine in the Bou Azer District has, since that time, produced the most amazing crystallized specimens, all displaying crystal forms slightly different to the old-time German counterparts. This stunning miniature specimen is a Calcite-lined vug with the Calcite almost entirely encrusted with stunning, sharp bladed crystals of the most intense cerise-pink Roselite imaginable. Individual crystals reach an impressive 5.5 mm in length. Under magnification the crystals are wonderfully translucent. Some show minor chipping to their edges, but most are in superb condition. This is an important specimen of this rare species. Ex Nick Hawes collection.
