The synthesized material is hard, optically flawless and usually colourless, but may be made in a variety of different colours. It should not be confused with zircon, which is a zirconium silicate (ZrSiO4). Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since 1976.\u003c\/em\u003e\u003c\/p\u003e","brand":"JWMetals ","offers":[{"title":"Default Title","offer_id":58320635199823,"sku":"153-GMPW","price":6.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2591\/2911\/files\/whitemixed__99571.1768355881.800.800.png?v=1785146945"},{"product_id":"oval-cabochon-black-onyx-10x14mm","title":"Oval Cabochon - Black Onyx - 8x6mm","description":"\u003cdiv dir=\"ltr\"\u003e\n\u003cp\u003e\u003cspan style=\"font-family: 'trebuchet ms', geneva; font-size: small;\"\u003eThis lovely deep black cabochon has been cut from natural Black Onyx, dyed to create a uniform blackness, and then polished to a high shine.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: 'trebuchet ms', geneva; font-size: small;\"\u003eBeing a cabochon (often shortened to cab) means it is not faceted, and has a domed front surface and a flat back\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: 'trebuchet ms', geneva; font-size: small;\"\u003eThey can't be fired with the clay, as they could crack or discolour if exposed to high temperatures, so need to be set in a bezel.
