{"product_id":"cobaltoan-dolomite-1","title":"COBALTOAN DOLOMITE","description":"Pink, cobalt-rich Dolomite is well known from Tsumeb mine but is nowhere near as common as some of the other carbonates at the mine. This miniature specimen is a delightful example. The Cobaltoan Dolomite is nicely crystallized and has a flesh-pink colour with a classic pearlescent lustre. When turned upside down it can be seen that the Cobaltoan Dolomite forms a thin 'skin' around a hollow core, representing either an epimorph - a cast after a long gone mineral - or, showing how when Dolomite forms from other carbonates such as Calcite there is a volume change. The Cobaltoan Dolomite crystals on the outer surface are small, but clearly visible, and show no obvious signs of damage.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780953645391,"sku":"CC15575","price":444.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC15575.png?v=1779745610","url":"https:\/\/crystalclassics.co.uk\/products\/cobaltoan-dolomite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
