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":"lab-created-gemstone-lavender-square","title":"Cubic Zirconia  Lavender Square","description":"\u003cp\u003e\u003cspan\u003eAn individual stone, either natural corundum, lab grown corundum, or cubic zirconia.
