Dolomite, Magnesite
Serra das Eguas, Brumado (Bom Jesus dos Meiras), Bahia, Brazil
Small Cabinet, 5.9 x 3.9 x 1.8 cm
AMAZING! Here, a superb dolomite twin is intergrown with a large rhomb of magnesite - another carbonate mineral that is usually an "accessory" mineral seen in small crystals (usually with uvites, in specimens from here), but here in a fine large crystal. So you have remarkable examples of BOTH MINERALS, together in one specimen, in a perfect size balance.
