It is graded \u003cb\u003eEye-Clean\u003c\/b\u003e on Stuller's quality scale — a calibrated stone cut to a standard millimetre size rather than a one-off crystal.\u003c\/p\u003e\u003cp\u003eBecause it is calibrated, we can usually replace or match it — useful for a pair, or if you want the same look in another size. Set it as the centre of your own ring in our ring builder, or buy it loose and keep it for a design of your own. Every stone ships insured, worldwide.\u003c\/p\u003e","brand":"Sapphire Row","offers":[{"title":"Default Title","offer_id":55471667085617,"sku":"OPAL-LAB:104457:G","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/9326\/5457\/files\/64580802_74cd3c8a-f77b-4fd4-ae60-e41658f2a18e.jpg?v=1785142437","url":"https:\/\/thesapphirerow.com\/products\/5x3-mm-oval-lab-grown-black-opal-cabochon-cut-eye-clean-quality","provider":"Sapphire Row","version":"1.0","type":"link"}
