{"product_id":"spurrite","title":"SPURRITE","description":"Spurrite is one of those mineral species which never really presents as good crystals, rather more of a type of rock. That said, this calcium silicate carbonate is rare and specimens from either of the Co-Type Localities are extremely hard to come by. This miniature specimen comes from one of those - Terneras mine, Velardeña, in Durango, Mexico - and was in the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021). Much of this piece is Spurrite, presenting as colourless to white crystalline masses similar to marble in appearance.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781230633295,"sku":"CC29939","price":111.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC29939_9a086539-4187-41d5-97ed-13c614406eb1.jpg?v=1783983088","url":"https:\/\/crystalclassics.co.uk\/products\/spurrite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
