{"product_id":"hambergite","title":"HAMBERGITE","description":"Hambergite is a very rare beryllium borate hydroxide mineral, typically found with other beryllium-bearing species within pegmatites. Crystals are usually small, except for a small number of exceptions, one of which is the famous Stak Nala area in the Haramosh Mountains in Gilgit-Baltistan, Pakistan. This magnificent large individual crystal from Stak Nala reaches a staggering 5.3 cm in length and comes from the superb systematic collection assembled by brothers Martin and Michael Günther (1951-2007 \u0026amp; 1956-2021). Tabular in form, it is actually orthorhombic and white in colour like Orthoclase feldspar, but with a slightly pearlescent lustre. This is a significant, museum quality crystal of this very rare species. It is mounted on an acryllic base for display and handling.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781229748559,"sku":"CC29835","price":2961.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC29835_0d7bbfa7-13e3-4840-9bba-d4906f7e5a5e.jpg?v=1783983019","url":"https:\/\/crystalclassics.co.uk\/products\/hambergite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
