{"product_id":"olivenite-with-cornwallite","title":"OLIVENITE   with CORNWALLITE","description":"This fine miniature from Wheal Unity, a mine neighbouring Wheal Gorland at St. Day in Cornwall, England, features Cornwallite which is one of the rarer copper arsenate species seen in these mines. The Cornwallite forms a pleasing matt, mid-green, box-work within which cavities are filled with glassy dark olive-green microcrystals of Olivenite. The whole assemblage appears to infill the centre of a partial nodule that is coated in more Olivenite along with dull black manganese oxides. Ex Malcolm Southwood collection, no. MS 2014.204, ex Cowen collection and ex Richard Barstow stock.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781377171791,"sku":"CC47958","price":178.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC47958_d6584fa0-0dfd-474e-a284-5905949c60b3.jpg?v=1783987755","url":"https:\/\/crystalclassics.co.uk\/products\/olivenite-with-cornwallite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
