{"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":46549602500783,"sku":"CC29835","price":4000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC29835.png?v=1770630872","url":"https:\/\/crystalclassics.com\/products\/hambergite","provider":"Crystal Classics","version":"1.0","type":"link"}
