{"product_id":"marcasite-round-cabochon","title":"Marcasite Round Cabochon","description":"\u003cp\u003eThe yellow-to-brown metallic sheen of this round marcasite gemstone is reminiscent of old sepia-toned photographs, making it a perfect choice for jewelry that has a vintage style.\n\nMarcasite is composed of iron sulfide and, while it is closely related to pyrite, it has a distinctly different crystal structure. Because its structure is orthorhombic (rather than cubic like pyrite), marcasite is less suitable for cutting and faceting and, in many jewelry applications, is actually yellow pyrite. When polished, the gemstone has a bright metallic luster, and ranges in color from pale yellow to brown. Jewelry made from marcasite\/pyrite dates back to ancient times and the folklore surrounding this gem holds that it can dispel negative energy and enhance communication skills.\n\nRound-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.\u003c\/p\u003e\n\u003chr\u003e\n\u003cb\u003eGemstone type:\u003c\/b\u003e Marcasite\u003cbr\u003e\u003cb\u003eStone shape:\u003c\/b\u003e Round\u003cbr\u003e\u003cb\u003eStone size:\u003c\/b\u003e 1mm, 2mm, 1.5mm\u003cbr\u003e\u003cb\u003eStone type:\u003c\/b\u003e Natural\u003cbr\u003e\u003cb\u003eColor:\u003c\/b\u003e Metallic Gray\u003cbr\u003e\u003cb\u003eEnhancement:\u003c\/b\u003e None (N)\u003cbr\u003e\u003cb\u003eMohs hardness:\u003c\/b\u003e 6–7.5\u003cbr\u003e\u003cb\u003eRefractive index:\u003c\/b\u003e Nil\u003cbr\u003e\u003cb\u003eSpecific gravity:\u003c\/b\u003e 4.8–5.2\u003cbr\u003e\u003cb\u003eMineral source:\u003c\/b\u003e PERU\u003cbr\u003e\u003cb\u003eCutting center:\u003c\/b\u003e Switzerland","brand":"Amadesa","offers":[{"title":"1mm","offer_id":52756950909274,"sku":"78128","price":12.15,"currency_code":"EUR","in_stock":true},{"title":"1.5mm","offer_id":52756950942042,"sku":"78129","price":12.15,"currency_code":"EUR","in_stock":true},{"title":"2mm","offer_id":52756950974810,"sku":"78130","price":12.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/78128.jpg?v=1763335870","url":"https:\/\/www.amadesa.com\/el-gr\/products\/marcasite-round-cabochon","provider":"Amadesa","version":"1.0","type":"link"}
