{"product_id":"rift-valley-oval-tanzanite-ring","title":"Rift Valley Oval Tanzanite Ring","description":"\u003cp\u003eTanzanite comes from a single stretch of hills in northern Tanzania, and an oval cut lets that rare blue-violet stretch along the finger. Flanking accents keep the stone company and shelter its edge, real work for a gem this soft. At 6 to 7 on the Mohs scale and with a clean cleavage plane, tanzanite is the most delicate faceted stone we set, so we build it low and protected. It is a natural stone, heated to bring up its colour as the whole trade does, and we would rather name that than imply otherwise. A right hand ring, not a bridal one. Select your metal and carat below.\u003c\/p\u003e\u003cp class=\"ds-disclosure\"\u003e\u003cstrong\u003eShown complete with a real Oval natural tanzanite center from 0.85 to 1.35 carat, from $1,989 all-in.\u003c\/strong\u003e The price is the finished ring: the setting, the tanzanite center you choose, and the labor to set and size it. Tanzanite is blue-violet zoisite at 6 to 7 on the Mohs scale, soft and cleavable, so we build it into protective settings, hand select every stone, and recommend removing the ring for the gym, the garden and rough work. Virtually all tanzanite is heat treated from a brownish rough to reach its blue-violet, a standard and permanent step we disclose plainly rather than claim the stone is untreated. These calibrated stones ship without an individual lab report.
