{"product_id":"cassiterite-22","title":"CASSITERITE","description":"Several clusters of lustrous black Cassiterite crystals are aggregated over a granitic matrix, from Bunny mine at Stenalees, St. Austell, Cornwall, a mine on the southern flanks of the Hensbarrow granite boss.  The individual Cassiterite crystals measure to 1.5 cm on edge and form well defined, lustrous pyramidal prisms protruding from a snowy white matrix of altered granite.  Because of fractures within the Cassiterite crystals and a slightly friable matrix, the specimen has been reinforced using a low viscosity superglue which is drawn into microscopic cracks by capillary pressure.  No glue is visible, giving the specimen a perfectly natural appearance.  The requirement for this treatment has, however, been reflected in its reduced price.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781240365391,"sku":"CC3257","price":178.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC3257_4282d955-078f-4b37-a397-060eda0d9de9.jpg?v=1783983934","url":"https:\/\/crystalclassics.co.uk\/products\/cassiterite-22","provider":"Crystal Classics UK","version":"1.0","type":"link"}
