Group of volkovskite crystals in parallel growth, colorless, transparent, with inclusions of hilgardite providing a bit of red color to the edges. This specimen comes from a finding that was recovered by a worker in the mine a years ago. Volkovskite is a very rare potassium and calcium chloroborate. Specimens of this size are very rare. Undoubtedly it is the best locality. We have analyzed by SEM-EDS this sample and we will send the results to the buyer.
