Dolomite, Magnesite
Serra das Eguas, Brumado (Bom Jesus dos Meiras), Bahia, Brazil
Cabinet, 9.5 x 5.5 x 5.3 cm
An unusual combination piece with robust, twinned dolomite crystals (the crystals looking like smushed barrels atop the rhombs), on top of stark white magnesite rhombohedra. The dendritic covering on some magnesite faces looks crystallized, even if micros, and could be another species.
