{"product_id":"london-blue-topaz-oval-diamond-halo-ring-3-8-ctw","title":"London Blue Topaz Oval Diamond Halo Ring (3\/8 ctw)","description":"An oval natural London Blue Topaz sits at the center of a lab-grown diamond halo, a full ring of diamonds circling the stone so that deep London-blue color reads even brighter. The accent stones are lab-grown diamonds (3\/8 ctw), disclosed alongside the natural London Blue Topaz with equal prominence. Take it in yellow or rose gold for a warm contrast against the deep blue, or in white gold or platinum to keep the whole ring cool and let the stone read even brighter. Its deep London-blue color is produced by irradiation followed by heat - a stable, permanent and standard practice in the trade - and every center stone is genuine natural topaz, not lab-created and not imitation. Blue topaz is a December birthstone and the traditional gift for a 4th wedding anniversary, so it works as a birthday or milestone piece as much as an everyday one. Topaz is an 8 on the Mohs hardness scale, so it stands up well to everyday wear, but it does have a natural cleavage direction - so avoid hard knocks, ultrasonic and steam cleaners, and prolonged strong sunlight. Clean it with warm water, mild soap and a soft brush, and store it apart from harder stones. It ships boxed and ready to give.\n\u003cdiv class=\"ds-minifaq\"\u003e\n\u003ch4\u003eQuick answers\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eStone:\u003c\/strong\u003e natural london blue topaz, 7 x 5 mm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSetting:\u003c\/strong\u003e an oval London Blue Topaz in a lab-grown diamond halo.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiamond accent:\u003c\/strong\u003e 3\/8 ctw lab-grown diamond, disclosed with equal prominence to the natural london blue topaz center.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMetal:\u003c\/strong\u003e 14K White Gold \/ 14K Yellow Gold \/ 14K Rose Gold \/ Platinum, solid gold or platinum (not plated).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs London blue topaz tough enough for everyday wear?\u003c\/strong\u003e Yes - topaz is an 8 on the Mohs hardness scale, harder than quartz gems like amethyst or citrine, so it wears well every day.
