{"product_id":"chalcopyrite-with-baryte-on-quartz","title":"CHALCOPYRITE with BARYTE  on QUARTZ","description":"As far as miniature specimens of crystallized Cornish Chalcopyrite go this is a stunner. It comprises a bed of finely crystallized frosted Quartz upon which sit inconspicuous grey-white freestanding bladed crystals of what appears to be slightly etched Baryte, but more noticeable are a line of perfect tetrahedral Chalcopyrite crystals individually reaching 1.1 cm on edge, with a larger one set off to one side of the specimen. These crystals are superb, sharp, and very 3-dimensional with a fine golden metallic surface appearance with minor dark grey coatings of possible Chalcocite. Beneath the bed of Quartz is a 5 mm thick layer of pale purple Fluorite sandwiched in green Chlorite. Ex Martin Kershaw Collection, previously labelled as South Caradon mine.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781476557135,"sku":"CC56128","price":703.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC56128_aed63168-3eed-4ddc-870c-55b2dfb725d3.jpg?v=1783990412","url":"https:\/\/crystalclassics.co.uk\/products\/chalcopyrite-with-baryte-on-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
