Torbernite, Margabal, Entraygues-sur-Truyère, Aveyron.

240,00

Torbernite, a phosphate of uranium and copper, forms crystals of a more or less dark green or clear and brilliant.
The crystals form here “helmets”, said flabelliformes, on gangue of grey quartz, and which show multiple facets. As you move the sample, they glow progressively, one after the other, for the most attractive effect. The research in 1997 by amateurs, on the prospect of the CEA discovered in 1950, gave place to these remarkable discoveries associated with smoked quartz. Mineral species from Margabal in Aveyron.
Floating, superb quality! Not to be missed!
