A classic and fine combination specimen from the 1960s finds at the Morro Velho Mine of Brazil. Lustrous, brassy, tabular cubanite crystals are richly and aesthetically scattered on the mounded matrix of glassy, yellow-green siderite blades and translucent, light gray dolomite rhombs. Some of the cubanites are beautifully iridescent and the large siderite is 2.2 cm. A highly representative and showy, two-sided piece from this well-known find and locale. Ex. Scott Williams Collection.
