RM360   Sphalerite with siderite

Troya Mine, Troi, Mutiloa, Gipuzkoa, Euskadi, Spain

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 several greenish siderite rhombohedral crystals (up to 9 mm.), with some dolomite. 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.


Size: 5,0 x 3,3 x 3,2 cm.
Main crystal: 10 x 9 mm.
Found in 1990.
