{"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":46578682527919,"sku":"CC3257","price":240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC3257.png?v=1771603110","url":"https:\/\/crystalclassics.com\/products\/cassiterite-22","provider":"Crystal Classics","version":"1.0","type":"link"}
