Description

Magnificent group of bournonite crystals of good size for the deposit, intact, brilliant and perfect in every way. A rare, high-quality specimen. The bournonite is associated with a few brown petalled siderite crystals typical of the area. Mineral found in the 1970s in one of the coal mines on the Matheysin plateau, of which La Mure is the main town, in the Isère department. Specimen from the Michel Maigrot collection. Here’s a video of these bournonite and siderite crystals from La Mure:
