{"product_id":"volborthite-with-brochantite","title":"VOLBORTHITE  with BROCHANTITE","description":"Excellent platy crystal rosettes of dark olive green Volborthite form a very rare combination with acicular turquoise green Brochantite crystals, from the relatively recent (2014-15) find at Milpillas mine at Cuitaca in Sonora, Mexico.  Overall, the rosettes of Volborthite crystals measure to 1.4 cm on snow white Dickite covering a light grey Limestone.  Volborthite from Milpillas mine is regarded as probability the best for its species in the world.  The Brochantite forms as very fine, hair-like acicular crystals around the base of the Volborthite, in long delicate sprays.  Despite being so fragile, the Brochantite is fairly well protected by the Volborthite.  A superb small miniature of Volborthite with Brochantite from the Milpillas mine in Mexico.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781486747983,"sku":"CC6328","price":3516.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC6328_532ab4c3-a9e4-4b7f-9037-bf97afefd8a3.jpg?v=1783991207","url":"https:\/\/crystalclassics.co.uk\/products\/volborthite-with-brochantite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
