{"product_id":"bertrandite-and-rhodochrosite-on-quartz","title":"BERTRANDITE and RHODOCHROSITE  on QUARTZ","description":"Bertrandite is a beryllium sorosilicate hydroxide which I am more used to seeing as individual rare crystals, especially in specimens from the British Isles. So when a specimen like this comes along, with a surface totally encrusted with superbly crystallised Bertrandite, seeing is believing! This choice large miniature is from Kara-Oba in the Karagandy Province of Kazakhstan. The Bertrandite forms creamy white translucent books and sprays to about 5 mm tall and covers a matrix of Quartz crystals averaging 5 cm long. One corner is punctuated with a patch of pale candy pink Rhodochrosite.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781239513423,"sku":"CC32470","price":222.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC32470_4e0023d8-891e-461b-a325-177830fe0ab8.jpg?v=1783983907","url":"https:\/\/crystalclassics.co.uk\/products\/bertrandite-and-rhodochrosite-on-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
