{"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":46549942927535,"sku":"CC49368","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC49368.png?v=1770653090","url":"https:\/\/crystalclassics.com\/products\/chalcopyrite-with-quartz","provider":"Crystal Classics","version":"1.0","type":"link"}
