{"product_id":"tetrahedrite-10","title":"TETRAHEDRITE","description":"Cavnic mine in Romania is well-known for razor sharp Tetrahedrite crystals. In modern mineralogical terminology Tetrahedrite is no longer an individual species, but a subgroup with many members. There are currently no specific records of which species within this subgroup the Cavnic mine specimens belong. This large miniature specimen is a Cavnic classic displaying dark grey metallic tetrahedral crystals to 1.3 cm on edge sat on a bright white Calcite-rich matrix. The Tetrahedrite crystals are really well-formed with some twinning also evident.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781232763215,"sku":"CC30187","price":333.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC30187_cf00b062-ee28-4a01-a21d-ea5750e4eac5.jpg?v=1783983500","url":"https:\/\/crystalclassics.co.uk\/products\/tetrahedrite-10","provider":"Crystal Classics UK","version":"1.0","type":"link"}
