{"product_id":"gem-a-portable-polariscope-c-2020s","title":"Gem-A Portable Polariscope (c.2020s)","description":"\u003cp\u003eThe Gem-A foldable portable polariscope embodies a compact, field-ready design developed for gemological work beyond the bench. Its foldable construction preserves a precise optical path while reducing bulk for transport, making it ideal for on-site gemstone inspections, field courses, and classroom demonstrations. The instrument combines a robust housing with carefully aligned polarizing components to deliver reliable plane-polarized light analysis in a portable format.\u003c\/p\u003e\n\u003cp\u003eDesigned for quick, accurate assessment, this polariscope enables rapid determination of isotropy versus birefringence in a wide range of gemstones. By viewing through the analyzer, users can discern singly refractive materials from doubly refractive ones, supporting swift material identification and preliminary quality assessment in travel, appraisal, or temporary lab settings. The compact build does not compromise the clarity of the optical path or the ease of sample manipulation.\u003c\/p\u003e\n\u003cp\u003eManufacturing details and provenance: Year of production is circa 2020s, with origin in London, United Kingdom, by Gem-A (Gemmological Association of Great Britain). This provenance aligns with Gem-A’s historical role in advancing portable teaching tools and field-grade instrumentation for professional gemology education and certification programs.\u003c\/p\u003e\n\u003cp\u003eThis is a museum archives and no unit is available for sale at this moment. \u003c\/p\u003e","brand":"Gems.studio","offers":[{"title":"Default Title","offer_id":51438055260480,"sku":null,"price":0.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0397\/2672\/files\/GEMA3.gif?v=1768291844","url":"https:\/\/gems.studio\/products\/gem-a-portable-polariscope-c-2020s","provider":"Gems.studio","version":"1.0","type":"link"}
