Inclusions and internal features are visible, consistent with natural haüyne and expected at this size and material type. Faceting is utilitarian rather than optimized for brilliance, prioritizing retention of weight and color over light performance. No evidence of coating, dye, or enhancement.\u003c\/p\u003e\n\u003ch3 data-start=\"852\" data-end=\"876\"\u003eGeological Context\u003c\/h3\u003e\n\u003cp data-start=\"877\" data-end=\"1331\"\u003eHaüyne is a feldspathoid mineral that forms in silica-poor, alkaline volcanic environments. These geological conditions are uncommon and geographically limited. Crystals form rapidly in volcanic systems, resulting in small, brittle material with a high fracture rate. The blue color is caused by sulfur radicals trapped within the crystal lattice during formation. This color mechanism is intrinsic and cannot be enhanced. Heat treatment destroys haüyne.\u003c\/p\u003e\n\u003ch3 data-start=\"1338\" data-end=\"1350\"\u003eRarity\u003c\/h3\u003e\n\u003cp data-start=\"1351\" data-end=\"1737\"\u003eFacet-grade Blue Haüyne is rare. Most material is opaque, heavily fractured, or too small to cut. Stones approaching one carat are uncommon, and stones retaining strong saturation at this size are scarcer still. Supply is sporadic and locality-dependent, with no commercial-scale mining and no expectation of increased availability. Once sold, comparable stones are not easily replaced.\u003c\/p\u003e\n\u003ch3 data-start=\"1744\" data-end=\"1769\"\u003eWear Considerations\u003c\/h3\u003e\n\u003cp data-start=\"1770\" data-end=\"2032\"\u003eMohs hardness is approximately 5.5–6. This stone is not suitable for daily wear and should be considered a collector specimen or set only in protective designs. Durability limitations are inherent to the species and are reflected in collector-market positioning.\u003c\/p\u003e\n\u003ch3 data-start=\"2039\" data-end=\"2050\"\u003ePrice\u003c\/h3\u003e\n\u003cp data-start=\"2051\" data-end=\"2098\"\u003e\u003cstrong data-start=\"2051\" data-end=\"2065\"\u003e$1,150 USD\u003c\/strong\u003e (approximately $1,210 per carat)\u003c\/p\u003e\n\u003cp data-start=\"2100\" data-end=\"2359\"\u003ePricing reflects the scarcity of near–one-carat facetable haüyne, strong natural color, absence of treatment, and limited, inconsistent market availability. This stone is offered as a collector mineral rather than a wearable substitute for sapphire or spinel.\u003c\/p\u003e\n\u003cp data-start=\"2100\" data-end=\"2359\"\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003eHaüyne does not have a standardized retail price guide. Pricing is based on collector-market comparables, size-relative scarcity, and the limited availability of facetable material. Stones approaching one carat with strong natural color trade infrequently and are priced accordingly.\u003c\/span\u003e\u003c\/p\u003e","brand":"Velcryn Gems","offers":[{"title":"Default Title","offer_id":48050947916008,"sku":"26-RCBH-1-1","price":1150.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5460\/8616\/files\/TopBlueHayune.95cts.jpg?v=1770677401","url":"https:\/\/velcryngems.com\/es\/products\/blue-hauyne-gemstone-0-95-carat-faceted-feldspathoid-collector-s-vault","provider":"Velcryn Gems","version":"1.0","type":"link"}
