Description

Fibrous dadsonite (XRD analysed) associated with bournonite and gemmy sphalerite on siderite. This specimen features dadsonite associated with sphalerite, making it even rarer giving that dadsonite is really hard to come by and found in a few localities worldwide.

Truly a superb sulfide combination specimen from a mineralogically unique alpine locale.
Cristosud's find.
