Item Description

A really attractive and interesting specimen from Brumado featuring classic golden colored twinned crystals of soft golden color Dolomite with selective alternating WATER CLEAR clarity and matte luster sitting atop white rhombic Magnesite crystals. Great quality, especially from the standpoint of the Dolomite, as the species is rarely seen in such well-formed twins, let alone GEM crystals. The largest Dolomite twin measures 1.3 cm. This is FINE quality twinned Dolomite, and the best of these pieces are some of the biggest and gemmiest twinned specimens from any world locality. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
