{"product_id":"cassiterite-23","title":"CASSITERITE","description":"Dolcoath was known as the Queen of Cornish Mines because of its size and wealth, being one of the largest mines in Cornwall by the end of the 1700's.  First a copper mine, as its depth increased the copper ore began to peter out and abandonment of the mine loomed.  But then tin ore was encountered and a whole new era of mining commenced.  This great miniature, richly encrusted in tiny Cassiterite crystals covering and impregnating a vein of opaque milky Quartz, is typical of the rich tin ore encountered in Dolcoath, a mine on the eastern outskirts of Camborne.  The Cassiterite crystals are mainly crude but are profuse and many well developed crystals can be seen, often giving a characteristic glint of golden-sherry along the black crystal edges.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780545028431,"sku":"CC12449","price":126.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC12449_79b8f81b-dd98-4ae1-a76b-be1b1796981b.jpg?v=1783969366","url":"https:\/\/crystalclassics.co.uk\/products\/cassiterite-23","provider":"Crystal Classics UK","version":"1.0","type":"link"}
