This lot is untreated, so the sky blue colour is natural — which is less common and worth noting for buyers who prioritise natural material.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eQ: What carat yield can I expect from Brazilian topaz facet rough?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eA: Yield depends on clarity and inclusions within each piece, but facet-grade rough is selected to maximise cuttable material. Expect roughly 20–40% recovery depending on the individual stone's geometry and internal features.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is topaz different from blue quartz or aquamarine?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Topaz (Mohs 8) is harder and denser than both quartz (Mohs 7) and aquamarine (Mohs 7.5–8), and its crystal structure is orthorhombic rather than trigonal or hexagonal — making it optically and physically distinct despite similar colour ranges.\u003c\/p\u003e","brand":"Gemstone Insider","offers":[{"title":"Default Title","offer_id":53042443288887,"sku":"TOPA-8765","price":5000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/6668\/8311\/files\/blue_topaz_facet_rough_for_lapidary.jpg?v=1790252924","url":"https:\/\/www.gemstoneinsider.com\/products\/sky-blue-topaz-facet-rough-untreated","provider":"Gemstone Insider","version":"1.0","type":"link"}
