Broad step facets reveal internal veils and fractures that are typical for pollucite and more apparent in step-cut styles. Face-up, the stone presents a calm, glassy appearance with minimal brilliance, consistent with the optical character of the species. The cut prioritizes material retention and stability over light performance.\u003c\/p\u003e\n\u003ch3 data-end=\"1312\" data-start=\"1284\"\u003e\u003cstrong data-end=\"1310\" data-start=\"1288\"\u003eGeological Context\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp data-end=\"1738\" data-start=\"1313\"\u003ePollucite is a cesium-rich mineral that forms in granitic pegmatites, where crystals grow in chemically specialized pockets during late-stage igneous processes. Facetable material is uncommon, as pollucite is more frequently encountered as mineral specimens or industrial cesium ore rather than gem rough. When cut, it is typically acquired by collectors who seek rare mineral species rather than conventional jewelry stones.\u003c\/p\u003e\n\u003ch3 data-end=\"1756\" data-start=\"1740\"\u003e\n\u003cstrong data-end=\"1754\" data-start=\"1744\"\u003eRarity\u003c\/strong\u003e\u003cstrong data-end=\"316\" data-start=\"306\"\u003e\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp data-end=\"758\" data-start=\"319\"\u003ePollucite is an uncommon cesium-bearing mineral that is seldom encountered in faceted form. While it is mineralogically significant as the primary ore of cesium, the overwhelming majority of pollucite occurs as opaque, fractured, or industrial-grade material unsuitable for cutting. Transparent crystals of sufficient size and stability to facet are rare, and a high proportion fail during cutting due to inherent brittleness and cleavage.\u003c\/p\u003e\n\u003cp data-end=\"1199\" data-start=\"760\"\u003eAs a result, faceted pollucite occupies a narrow and specialized collector market. Availability is irregular and dependent on sporadic recovery from chemically extreme granitic pegmatites rather than ongoing commercial production. Stones of this size with usable transparency and coherent geometry are not routinely replaceable and typically circulate through collector and specialty mineral channels rather than mainstream gemstone trade.\u003c\/p\u003e\n\u003ch3 data-end=\"2111\" data-start=\"2082\"\u003e\u003cstrong data-end=\"2109\" data-start=\"2086\"\u003eWear Considerations\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp data-end=\"2404\" data-start=\"2112\"\u003ePollucite has a hardness of approximately Mohs 6.5 and is not suited for daily-wear rings. If set, it performs best in protected designs such as bezels or deeply seated mounts, or in lower-impact wear categories like pendants. This stone is offered first and foremost as a collector specimen.\u003c\/p\u003e\n\u003ch3 data-end=\"2421\" data-start=\"2406\"\u003e\u003cstrong data-end=\"2419\" data-start=\"2410\"\u003ePrice\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong data-end=\"2419\" data-start=\"2410\"\u003e$225\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-end=\"2929\" data-start=\"2422\"\u003ePollucite does not have a standardized retail price guide. Faceted material trades within a narrow collector market where value is based on size, cut integrity, transparency, and availability rather than brilliance or durability. Pricing for this stone reflects its larger carat weight, natural untreated condition, and the limited availability of facetable pollucite, while accounting for internal features emphasized by the step cut. It is priced for a collector buyer rather than mass-market jewelry use.\u003c\/p\u003e","brand":"Velcryn Gems","offers":[{"title":"Default Title","offer_id":48052166492392,"sku":"26-TP-1-1","price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5460\/8616\/files\/PolluciteTrapazoid1.94cts.jpg?v=1770745250","url":"https:\/\/velcryngems.com\/fr\/products\/pollucite-gemstone-1-94-carat-trapezoid-step-cut-collector-s-vault","provider":"Velcryn Gems","version":"1.0","type":"link"}
