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\u003eCare \u0026amp; Setting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eZircon can be brittle despite its excellent brilliance.
