An exceptionally beautiful radiating spray of lustrous perfectly-terminated Aragonite crystals that have no damage. Thecrystal habit is indicative of the type of aragonite from Tsumeb which has lead included within it (known as Tarnowitzite). These crystals also fluoresce a beautiful red in short wave UV. A great specimen, and much better in person! The slight yellow-green color may be due to the presence of minute traces of nickel, hence this is probably of the more specific varietal known as nicholsonite. Purchased from the Zweibels in 1978
