Metatorbernite

Exceptional cabinet-size specimen of very nicely-crystallized green metatorbernite crystals on matrix from the famous Margabal mine in France. What I especially like about this one compared to so many other Margabal torbernites is how “individualized” the crystals are all on matrix. Hard to get in this quality from the locality these days. Measures ~100,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Rare!
