Uranocircite

Truly superb specimen of very well-crystallized, 3-dimensional, undamaged Uranocircite from the well-known Sao Pedro claim in Minas Gerais, Brazil. For this species at the locality this is basically as good as it gets! Excellent and very aesthetic specimen. Measures ~100,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Rare!
