An outstanding cluster of reticulated, twinned Hambergite with gorgeous satiny luster, backed onto minimal matrix. The main crystal is an amazing 7 cm long, and it is fairly translucent with some gemminess at the termination. This rare beryllium borate is quite good for the locality, illustrating the reticulated growth patterns more commonly seen in Cerussite. Hambergite is also uncommon from the locality, as well - not many good specimens have been found, to my knowledge, and they were a long time ago now. It is on Feldspar, with a bit of Tourmaline. Excellent for the species. Comes with a custom base.
