{"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":58110718378319,"sku":"CC58836","price":370.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC58836.jpg?v=1784289649","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-546","provider":"Crystal Classics UK","version":"1.0","type":"link"}
