The quartz itself carries an unusually dark, saturated tone with crisp, clean edges, while the fine, frost-like bertrandite clusters add a delicate counterpoint to its weight and depth.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\" data-sourcepos=\"26:1-26:293;1185-1477\"\u003eThe Kara-Oba deposit ceased operation in 1996, and this particular pairing of smoky quartz with beryllium silicate minerals became correspondingly harder to find once the mine closed. For collectors, this is not simply a striking crystal — it is a geological record with a clear closing date.\u003c\/p\u003e","brand":"Taiwan Mineral Shop by The Brothers' Stones","offers":[{"title":"Default Title","offer_id":43682540683327,"sku":"SQKAZA01","price":5250.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/3779\/2575\/files\/Smoky_quartz_Kazakhstan-SQKAZA01_1.jpg?v=1786025448","url":"https:\/\/mineral-taiwanshop.thebrothersstones.com\/en\/products\/kazakhstan-smoky-quartz","provider":"Taiwan Mineral Shop by The Brothers' Stones","version":"1.0","type":"link"}
