{"product_id":"gorceixite","title":"GORCEIXITE","description":"The Clara mine in Rankach Valley, Oberwolfach, Black Forest, Baden-Württemberg, Germany is a mineral collectors dream locality. It has produced more mineral species (471) than some countries and 16 of those were first described from the mine - as the Type Locality. This large thumbnail specimen presents a very rich coverage of turquoise blue Gorceixite microcrystals coating Quartz. Gorceixite - barium aluminium phosphate hydroxide - can occur in a range of different colours, the blue usually being attributed to traces of copper.  The specimen has not been analysed, but an arsenate analogue - Arsenogorceixite - was first described from Clara mine and looks identical. A solid-solution series occurs between the two species so there is a possibility that this specimen also contains Arsenogorceixite. Ex Martin and Michael Günther collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781190558031,"sku":"CC27491","price":222.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27491_b3e7c7b0-0d9c-4833-a20b-9c5751307e28.jpg?v=1783980931","url":"https:\/\/crystalclassics.co.uk\/products\/gorceixite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
