{"product_id":"calcite-546","title":"CALCITE","description":"This unusual, stepped aggregate of nailhead-shaped Calcite crystals is like a mini Giant's Causeway. It comes from the famous Hilton mine in Cumbria, England, where everyone assumes that the only mineral to be found is amber-coloured Fluorite. This interesting specimen was collected from Hilton mine in the mid-1970s from North Vein by Lindsay Greenbank and Michael Sutcliffe and was kept by Lindsay in his private collection, as no. LG.261. Internally, a large individual cream-white Calcite crystal forms the core about which the smaller, greyish, nailhead Calcite crystals have grown in a stepped arrangement. In overall very good condition this is a quite unusual Hilton mine piece and with great provenance - Lindsay Greenbank's accompanying label provides very precise details of where it was found. Ex Dr Stephen Crook Collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46793898295471,"sku":"CC58836","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC58836.png?v=1780560818","url":"https:\/\/crystalclassics.com\/products\/calcite-546","provider":"Crystal Classics","version":"1.0","type":"link"}
