Malachite pseudomorph after Azurite (ex Rolando Gioia Collection)

Item Description

A classic example of stark green Malachite pseudomorphing after Azurite from the famous locality at Touissit. The prismatic, thick crystals are completely pseudomorphed, but there are actually some smaller Azurite crystals on the back (second deposition). The piece is a good reference specimen of the material, as it's not 100% damage free, but it's still in good shape. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
