Hambergite is a rare accessory mineral in gem pegmatites. This elongated pearlescent and translucent, white crystal is doubly-terminated and also hosts a 1.4 cm long, elbaite crystal (itself doubly-terminated!). hambergite is a beryllium, borate and sharp elongate crystals are known from only a few localities. For Nepal, this specimen is off the charts, really good, rivalling material from Pakistan and Tajikistan in quality. The elbaite is ditstinctly, however, from this mine. Ex. Paul Stahl Collection
