9.0 x 7.0 x 4.8 cm. An OLD-TIME, VERY RICH and showy chrome species combination specimen from the Type Locality - Berezovsk, Urals Region, Russia. This classic may contain 3 chrome species, 2 of which, are VERY RARE. One half of the specimen is covered with red to orange crocoite crystals. This specimen has a VERY RICH section of pistachio-green vauquelinite, a RARE lead, copper, phosphate, chromate. The specimen may also contain embreyite, an ULTRA RARE lead, phosphate, chromate: although not analyzed, we believe that it may be either the tan or black microcrystals on the matrix. The specimen would have to be X-rayed for confirmation of course, its just a likelihood given the age and overall appearance of the material. CHOICE, old material for the species and locality. This rich and showy old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe. Accompanied by an old, handwritten German label.
6.0 x 5.4 x 4.6 cm. This specimen is from the type locality for all three species here, and features rich zones of all three as well. It has prismatic orange crocoite crystals to 2 cm in length. Olive green vauquelinite occurs as chalky, green growths on crocoite. Nestled in a vug are minute black embreyite crystals. Ex. Harvard University and Phil Scalisi Collections.
7.7 x 4.9 x 4.0 cm. A very rich specimen, with rich pistachio-green Vauquelinite microcrystals all over the piece, and minute druses of embreyite microcrystals as well (they are orange, and seem intermixed quite liberally on the righthand side). This is the type locality for both species.
5.2 x 5.1 x 3.8 cm. 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.
11.5 x 7.1 x 6.0 cm. This large specimen is an excellent, important example of crocoite from the type locality for the species. Note the robust, sharp, stereotypic crystal habit so different from that which we normally see in the far more common Australian material. These stand out, dramatically, from most crocoite you will see from Australian localities. The crystals are to 1.4 cm, on matrix. Also, you have rich pistachio-green druse of the very rare phosphate-chromate Vauquelinite all over the specimen. Discovered in the early 1800s, these are some of the oldest well-studied lead mineral species and both are lead chromates. Ex. Ed N. Harrison Collection.
A very important specimen with several identified patches of microcrystallized but eye-visible EMBREYITE present. This is an extremely rare mineral and I am told it was identified on old specimens from this locality in museum collections, and is very rarely seen for sale. This specimen is extremely rich. Aside from the two small vugs there are isolated spots of embreyite elsewhere as well. MOREOEVER, the Vauquelinite on this specimen, in the form of spherical green balls atop the crocoite vug, is also quite exceptional and is the richest example of this mineral I have yet seen from the location (it is usually just greenish splotches on broken crocoite!). So, we have TWO significant rarities on what is, overall, a fairly attractive specimen of crocoite from the TYPE LOCALITY for ALL THREE SPECIES 6.5 x 3.4 x 2.9 cm
This matrix is heavily invested with massive crocoite, but a protected vug in the center has several prismatic, lustrous and gemmy, reddish- orange, crystals to 1.5 cm in length. Surrounding the vug and then running in veins throughout are rich veins and surface carpets of olive green vauqelinite, a rare lead-copper species. Over two hundred years ago, crocoite was first described from this locality. At that time, Vauquelinite was found in some quantity but it has not, to my knowledge, been found in any recent reworkings of the locality. 8.8 x 5.8 x 3.8 cm
A very rich specimen from this famous lead deposit, with rich postachio-green Vauquelinite microxls all over the piece, and minute druses of embreyite microxls as well (they are orange, and seem intermixed quite liberally on the righthand side) . The even rarer cassedanneite is red and although I have not analysed the red micros here, it is possible they are that species. Type Locality for both species!
