{"product_id":"hydroxylherderite-5","title":"HYDROXYLHERDERITE","description":"An interesting thumbnail twin of a creamy, opaque Hydroxylherderite crystal measuring to 2.8 cm, from Barro do Salinas in Coronel Murta, Brazil.  Hydroxylherderite is a calcium-beryllium phosphate hydroxide [CaBe(PO4)(OH)] whereas Herderite is a calcium-beryllium phosphate fluoride [CaBe(PO4)F],  hence the “Hydroxyl” prefix signifying the dominance of hydroxide over fluorine.  It is a species associated with granite pegmatites, typically occurring as small indistinct crystals, hence specimens such as this are exceptional for the species.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781517910351,"sku":"CC8515","price":222.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC8515_93147e35-944e-4aa0-bc1e-3fec7eeadf06.jpg?v=1783992575","url":"https:\/\/crystalclassics.co.uk\/products\/hydroxylherderite-5","provider":"Crystal Classics UK","version":"1.0","type":"link"}
