Nearly every blue zircon sold has been heated, and the color is stable in everyday wear. One tip: keep it away from tanning beds and UV nail lamps. Strong ultraviolet can give it a temporary brownish cast, which a short time under an ordinary incandescent bulb restores.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDigital Gem Passport\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOTZ-2026-01738\u003c\/p\u003e","brand":"Otzera","offers":[{"title":"Default Title","offer_id":51229655433463,"sku":"OTZ-2026-01738","price":1295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/9999\/6919\/files\/OTZ-2026-01738-1.jpg?v=1790633140","url":"https:\/\/otzera.com\/products\/4-05-ct-cambodian-blue-zircon-oval-mixed-cut","provider":"Otzera","version":"1.0","type":"link"}
