An excellent thumbnail of this rare uranium mineral, featuring sharp, well-formed lemon yellow to green crystals of uranocircite from a small find around 10-15 years ago at the Sao Pedro claim in Brazil which probably produced the best specimens ever of this mineral. Measures ~20,000 CPM on my Ludlum Model 3 survey meter with the 44-9 probe. Rare!
