{"product_id":"blue-topaz-necklace-diamond-halo","title":"Blue Topaz Necklace with Diamond Halo","description":"\u003cp\u003eA 7 mm round London blue topaz sits flush in a polished bezel, ringed by a full circle of natural diamonds — a quarter carat of them, set all the way around with no gap at the bottom. The bezel does the work a claw setting cannot: it wraps the girdle completely, so the stone is protected on every side and the outline stays clean against skin.\u003c\/p\u003e\n\u003cp\u003eThis is the largest and brightest piece in the collection, and the one that reads from across a room. On an adjustable 16-to-18-inch cable chain in solid 14K white, yellow or rose gold, or platinum.\u003c\/p\u003e\n\u003cp\u003eArrives in Diamond \u0026amp; Sapphire gift packaging, ready to give — blue topaz is the December birthstone and the traditional fourth-anniversary stone, so it carries a reason as well as a colour.\u003c\/p\u003e\n\u003cp\u003eCentre stone: 7 mm round-cut natural blue topaz. Setting: bezel-set centre with a full round diamond halo. Pendant 11.9 x 11.8 mm. 1 mm cable chain with a lobster clasp, adjustable to 16 or 18 inches, included.

The colour does not fade with normal wear. Topaz has perfect basal cleavage: clean with warm soapy water and a soft brush, and keep it away from ultrasonic cleaners, steam and sudden temperature change.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eStated gemstone dimensions and diamond carat weights are nominal; actual stones may vary slightly within normal manufacturing tolerance.
