{"product_id":"sperrylite-6","title":"SPERRYLITE","description":"Sperrylite is a platinum arsenide and this good-sized miniature is from the Talnakh Cu-Ni Deposit in the Eastern-Siberian Region, Russia.  It is a magnificent specimen, with many fine sperrylite crystals lining an L-shaped open vug in a dark matrix of what is though to be a mixed matrix of anhedral iridescent chalcopyrite and magnetite.  The Sperrylite crystals range from a few mm to 0.9 cm on edge and form well defined cubic (isometric) crystals with their corners modified to the octahedron.  Their faces tend to be crazed by a pattern of shallow furrows and all are of a pure metallic silver with a bright reflective metallic lustre.  Sperrylite is a rare platinum mineral which so often is found only as small crystals, often at the more microscopic level.  This is a specimen of museum quality and is well priced for such a splendid well-crystallised Russian Sperrylite.  It comes with a collection of previous labels and a custom milled acrylic base into which the specimen securely slots into its contoured profile.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545288495279,"sku":"CC20784","price":6000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20784.png?v=1770378222","url":"https:\/\/crystalclassics.com\/products\/sperrylite-6","provider":"Crystal Classics","version":"1.0","type":"link"}
