Kounrad Massif, Balqash (Balkhash; Karatas; Prebalkhashie) Region, Zhezqazghan Oblysy (Dzezkazgan Oblast'; Dzhezkazgan Oblast'; Djezkazgan Oblast'; Jezkazgan Oblast'), Kazakhstan This is a superb piece in every way - both for quality of the large bertrandite crystals and for their aesthetic arrangement on matrix. It is quite a significant piece, even aside from pedigree. 4.7 x 2.7 x 2.6 cm Mindat.org Photo of the Day - 11th Feb 2009 |
