SPHALERITE, DOLOMITE, CALCITE

A very brilliant specimen of this classic Basque mine. It shows a sphalerite matrix partially covered with brilliant sphalerite crystals, with slightly curved faces and edges. Good transparency and toasted honey color. It is accompanied by siderite, calcite and dolomite in rhombohedral crystals. A very aesthetic specimen. Troya Mine was closed in 1993, only a few years before these specimens were collected in 1990. Nowadays the mine is collapsed and flooded. This specimen was in a former German mineral collection since then. EX. EMILIO RODENAS.
