- Wolframite, Dolomite
- Miniature, 4.8 x 3.5 x 3.4 cm
- Panasqueira Mine - Couto Mineiro da Panasqueira, Panasqueira, Covilha, Castelo Branco District, Portugal
An EXCELLENT and CLASSIC cluster of lustrous, blocky, parallel-growth wolframite crystals from Panasqueira, Portugal. The wolframites are nicely accented and complimented by two generations of dolomite. It almost looks like a cogwheel bournonite, in one view. Ex. George Elling Collection.
