{"product_id":"aurora-halo-emerald-cut-blue-topaz-ring","title":"Aurora Halo Emerald-Cut Blue Topaz Ring","description":"\u003cp\u003eA halo of small accents rings an emerald cut blue topaz and gathers extra light around its cool blue steps. Wear it as a cocktail ring or the crown of a stack on the right hand. Choose London Blue, Swiss Blue or Sky Blue, three real topaz varieties separated only by depth of colour. Every one is irradiated and warmed to its blue, which is standard practice across the trade, and we say so rather than imply the stone is untouched. The halo shelters a brittle stone that cleaves under a knock. Select your metal, carat and variety below and we finish it to size.\u003c\/p\u003e\u003cp class=\"ds-disclosure\"\u003e\u003cstrong\u003eShown complete with a real Emerald-Cut blue topaz center from 0.7 to 2 carat, a london blue topaz (deep steely blue), swiss blue topaz (vivid electric blue), or sky blue topaz (pale watery blue), your choice, from $2,019 all-in.\u003c\/strong\u003e The price is the finished ring: the setting, the blue topaz center you choose, and the labor to set and size it. Blue topaz rates 8 on the Mohs scale, so it is hard, but it has a perfect cleavage plane, which means a sharp knock can split it; a protective setting suits it and it is best removed for gardening, the gym, and rough work. Almost all blue topaz is irradiated and heat treated from colourless topaz to reach its blue, a standard, stable and permanent step that is cleared for sale before the stone ships, and we disclose it plainly rather than claim the stone is untreated. These calibrated stones ship without an individual lab report.
