{"product_id":"cobaltite-in-pyrrhotite-chalcopyrite","title":"COBALTITE in PYRRHOTITE-CHALCOPYRITE","description":"Known for over two centuries and still considered to be the premier locality for perfect Cobaltite crystals. Tunaberg in Södermanland, Sweden was, during the early 19th century, a key destination for travelling mineralogists who wanted to obtain crystals of this rare cobalt-bearing species. Bearing a classic, single, bright metallic silvery Cobaltite crystal measuring 9.5 mm on edge, hosted in bronze-metallic yellow Pyrrhotite-Chalcopyrite matrix, this very large miniature, but perfectly displayable specimen is a rare example of a superb Cobaltite crystal still in matrix. The crystal of Cobaltite stands out from the surrounding sulphides, displaying a cube truncated by a dodecahedral face, and faintly striated. Exceptionally bright for its undoubted age and with only the tiniest of microscopic chips this is a magnificent museum quality specimen of a historic species usually seen as loose individual crystals.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":58110412947791,"sku":"CC4569","price":4837.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC4569_9fee0ab7-f070-4e0a-b7cc-0e289905c6e4.jpg?v=1784299830","url":"https:\/\/crystalclassics.co.uk\/products\/cobaltite-in-pyrrhotite-chalcopyrite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
