{"product_id":"betekhtinite-3","title":"BETEKHTINITE","description":"Originally described from two mines in Germany during the 1950s it was not until 1998 that really rich highly visible crystallized aggregates of Betekhtinite (a rare copper-iron-lead sulphide) were discovered, in the Dzhezkazgan Mining District in the Karaganda Region of Kazakhstan and these have never been bettered since. This excellent miniature size specimen, is a mass of aligned black metallic bladed Betekhtinite crystals forming a column-like structure and terminated by numerous individual euhedral (complete) crystals and cleaved tips, the latter due to contact with the original in-situ host rock. The rich copper-zinc deposit at Dzhezkazgan is hosted in a succession of Upper Carboniferous sandstone bodies. This is a remarkably good specimen from that important find. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021).","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781191082319,"sku":"CC27523","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27523_1ae3d2d3-b240-4549-b802-c1ca14306d3b.jpg?v=1783980953","url":"https:\/\/crystalclassics.co.uk\/products\/betekhtinite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
