{"product_id":"chalcopyrite-with-quartz","title":"CHALCOPYRITE   with QUARTZ","description":"This fine cabinet-sized display Chalcopyrite and Quartz is documented as from Osarizawa mine in Akita Prefecture, but I have found nothing comparable online suggesting perhaps that it is from another of Japan's famous copper mines within that Prefecture. Consisting a rich vein of bright golden metallic Chalcopyrite and white Quartz the upper display surface is covered in well-crystallized tetragonal Chalcopyrite with individual crystals reaching 1 cm on edge. The crystals are extremely well-defined for this species but there is damage to the edges of some crystals with the bright underlying Chalcopyrite shining through. The Quartz forms crusts composed of small terminated crystals. A fine Japanese classic, possibly dating back to the 1960s or 1970s. Ex David Hardman collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781407547727,"sku":"CC49368","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC49368_687865e5-4924-43ca-9d6b-50d985a2ab57.jpg?v=1783988370","url":"https:\/\/crystalclassics.co.uk\/products\/chalcopyrite-with-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
