{"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":46584039375023,"sku":"CC12449","price":170.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC12449.png?v=1771840840","url":"https:\/\/crystalclassics.com\/products\/cassiterite-23","provider":"Crystal Classics","version":"1.0","type":"link"}
