Excellent, large, rich specimen of well-crystallized Haiweeite on pegmatite matrix (quartz and microcline) from the one-time, probably best-of-species find at Teófilo Otoni, Minas Gerais, Brazil. Very brightly fluorescent under all wavelengths of U.V. light! Very good for this uncommon uranium mineral. Rare!
