Description

That's an impressive specimen! The matrix consists mainly of sphalerite with pyrite and some quartz. On top there is a large cluster of extremely bended calcite-crystals. They're colored by inclusions of jamesonite and overgrown by 1.000s of small calcites as a second generation. The cluster is crystallized all around and has only one or two small contact. The rest is undamaged. At the clusters base you can find crystallized jamesonite also. It's a fantastic specimen and easy to display in variouse positions.
