Wulfenite with Siderite

A striking cluster of bicoloured Wulfenite crystals from the Příbram mining district in the Czech Republic. Bipyramidal Wulfenite crystals measuring to nearly 8 mm with light greyish central prisms and pale butter-yellow-caramel pyramidal terminations rest on a matrix of dark metallic grey Galena, Sphalerite and layered rock matrix. Complete and partly etched orange-tan to biscuit tan lenticular Siderite crystals are richly scattered over the surface. An interesting large miniature from Příbram displaying some unusual and well-formed Wulfenite prisms.
