The display face of a massive to crystalline dolomite matrix is liberally covered with siderite in two forms: somewhat flattened rhombs in parallel and small, green-brown rhombs. Also present are terminated gypsum crystals rendered gray by boulangerite inclusions. These gypsum crystals are all terminated; the longest is doubly terminated example and measures 1.9 cm. Self standing for perfect display. Superb condition.
