This sample shows two mineralized sides. A first one totally covered by brilliant sphalerite crystals, with complex and curved faces and edges. Good transparence with toasted honey tones. Accompanied by few crystals of siderite. The other specimen side is partially covered by several yellowish-white dolomite crystals and flattened, brilliant and defined rhombohedrons of siderite with greenish tones.
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.
