Bertrandite, Quartz and Pyrite - Kara-Oba deposit, Betpakdala Desert, Karaganda Oblast, Kazakhstan (#:FERR0819)

Cluster with rich coverage of pearl white Bertrandite xls, spread over smoky Quartz xls, and associated with Pyrite in cubic xls. The specimen is in pretty good shape. These pieces appeared on the market around ten to twenty years ago and seemed quite common then, but they actually were old pieces that became available after the end of the former USSR. They are now absolutely hard to find, expecially with this quality.
