An exceedingly rare and old specimen (both label and specimen are numbered #295 in the American Museum acquisitions, dating to the mid-1800s!), of clinochlore from Russia. I Have never seen such a thing on the market. It is way beyond other examples of the species in size, really just unprecedented. The crystal has a metallic, unique maroon color to it. It seems to be complete on the front, contacted in back, and complete all around as well (the notch you see is contact, not a "bite" out of it). Ex AMNH exchanged into the collection of dealer/collector Lawrence Conklin. Thanks to Tim Blackwood who did some research and he did find a modern name of Poldnevaya village, Ekaterinburg (Sverdlovsk), Ekaterinburgskaya (Sverdlovskaya) Oblast', Middle Urals, Urals Region, Russia as a locality given on Mindat.org. On a hunch I did a Mindat.org locality search for "Pold" and came up with the above locality. It would appear that Polnevaya is a new spelling for Poldnewaja. I believe the pronunciations would be the same. Clinochlore isn't listed for the Mindat.org location, but I believe it to be correct.
