A very nice specimen of this classic Basque mine. It shows a dolomitic matrix partially covered by brilliant sphalerite crystals, defined faces and slightly curved edges. Excellent transparence and toasted honey color. It is accompanied by some greenish siderite rhombohedral crystals and dolomite crystals. A complete and brilliant specimen from this mine. From the Manchion Collection.
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.
