{"product_id":"lagoon-oval-blue-topaz-ring","title":"Lagoon Oval Blue Topaz Ring","description":"\u003cp\u003eAn oval blue topaz stretches along the finger and throws a wide, watery flash, edged by accents that keep it company. Think of it as an everyday cocktail ring, not a proposal. Your choice of blue runs from the deep London through the vivid Swiss to the pale Sky, each a real topaz and each honestly the same stone at heart. Blue topaz gets its colour from irradiation and heat, a routine and lasting step, and we would rather name it than imply the stone is untouched. Topaz splits along a cleavage plane, so the accents shelter its edge. Pick your metal, carat and variety below.\u003c\/p\u003e\u003cp class=\"ds-disclosure\"\u003e\u003cstrong\u003eShown complete with a real Oval blue topaz center from 1 to 2.4 carat, a london blue topaz (deep steely blue), swiss blue topaz (vivid electric blue), or sky blue topaz (pale watery blue), your choice, from $1,589 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.
