{"product_id":"14k-3-09ctw-oval-tanzanite-eternity-band","title":"14K 3ctw Oval Tanzanite Eternity Band","description":"\u003cp\u003eTanzanite exists in exactly one place on Earth—a five-square-mile stretch of northern Tanzania, near Kilimanjaro, where tectonic pressure and trace amounts of vanadium created something geologists call a \"geological phenomenon.\" This eternity band holds 13.09 carats of it, fifteen oval stones set in a continuous loop of 14K yellow gold, each stone averaging just under a carat. The violetish-blue shifts depending on angle and light source—more purple under incandescent, more blue in daylight—a property called pleochroism that tanzanite shares with very few other gems.\u003c\/p\u003e\n\u003cp\u003eThe setting is shared-prong construction, minimal metal between stones to maximize the violet corridor effect. At 5.91 grams, it has presence without bulk—a ring that reads as serious jewelry from across a room. Wear it as a statement piece or stack it against a plain gold band.\u003c\/p\u003e\n\u003cp\u003eIGI certified the stones in August 2025, noting the following: slightly included clarity (normal for stones this size), heat treatment (standard practice since tanzanite's 1967 discovery), and a blue color that made Tiffany \u0026amp; Co. bet their reputation on this stone fifty years ago.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSapphire's younger, rarer, more interesting sister.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMETAL:\u003c\/strong\u003e 14K yellow gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWEIGHT:\u003c\/strong\u003e 5.91 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSIZE:\u003c\/strong\u003e 8.25 US \/ 58 EU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRESIZING:\u003c\/strong\u003e No—full eternity setting cannot be sized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSETTING:\u003c\/strong\u003e Shared prong, continuous band\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c!-- notionvc: f5d51df9-fc3c-4ce8-bcbc-38ff491bb4e9 --\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!-- notionvc: 002e412c-9c6b-4f6d-afb6-b298eb29b7bb --\u003e\u003c\/p\u003e","brand":"Stones + Orbits","offers":[{"title":"Default Title","offer_id":48491188879612,"sku":null,"price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/9295\/3084\/files\/StonesAndOrbits_OvalTanzaniteEternityBand_Hero.png?v=1763219553","url":"https:\/\/stonesandorbits.com\/products\/14k-3-09ctw-oval-tanzanite-eternity-band","provider":"Stones + Orbits","version":"1.0","type":"link"}
