An old-time, very rich and fine chromium species combination specimen from the Type Locality - Berezovsk, Urals Region, Russia. This classic may contain 3 chromium species, 2 of which are very rare. Gemmy and lustrous red to orange crocoite crystals cover part of the specimen. This specimen has a very rich section of pistachio-green vauquelinite, a rare lead, copper, phosphate, chromate. The specimen may also contain embreyite, a very rare lead, phosphate, chromate: although not analyzed, we believe that it may be the black microcrystals on the matrix. The specimen would have to be X-rayed for confirmation of course, it's just a likelihood given the age and overall appearance of the material.
