Dolomite Cast After Calcite

Very classic and sought after Dolomite cast from the Tsumeb Mine, which is famous for these specimens. The cast is a lustrous pink-brown colour, showing a double dome of Dolomite replaced lenticular intergrown Calcite crystals. The hollow underside of the specimen has impressions of the original Calcite crystals largely overgrown by a sparkling druse of Dolomite crystals. A fine Dolomite cast from the mine.
