{"product_id":"dioptase-on-mottramite","title":"DIOPTASE   on MOTTRAMITE","description":"This is a really unusual combination of species for Tsumeb mine, and in a display-worthy cabinet-sized specimen too. A hard grey limestone rock matrix forming a shallow dome-like form is coated uniformly with a thin microcrystalline layer of murky-green, to leaf-green Mottramite, terminated by a dull greyish surface coating. Upon this are scattered thousands of bright sparkling emerald-green Dioptase crystals. Although small (1 to 1.5 mm in size), these are perfectly formed and make a superb display, contrasting with the dull Mottramite layer below. Ex Weyand collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584971002031,"sku":"CC52732","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC52732.png?v=1771867792","url":"https:\/\/crystalclassics.com\/products\/dioptase-on-mottramite","provider":"Crystal Classics","version":"1.0","type":"link"}
