The white gold split shank divides into two parallel diamond-paved rows on each shoulder, creating a wide, sparkling frame that transitions from the stone's face level down to a clean, comfortable band with exceptional craftsmanship in each individual stone setting. The yellow gold prong caps, visible from the front and profile, create a deliberate two-tone signature that distinguishes this mounting from conventional single-metal settings and frames the tanzanite's extraordinary color with maximum metallic contrast.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003eAbout The Stone\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003eThis 20.45 carat emerald-cut tanzanite is an exceptional specimen by any standard — tanzanite is found exclusively in a single location on earth, a small mining area near Merelani in northern Tanzania at the foot of Mount Kilimanjaro, and geologists estimate that the remaining deposits will be exhausted within the next generation, making tanzanite of this quality genuinely and permanently finite. The emerald cut is the ideal shape for a tanzanite of this depth of color, as its broad open table and clean step facets allow the stone's characteristic trichroism — its ability to display blue, violet, and burgundy simultaneously depending on the viewing angle — to be observed as a rich, shifting color field rather than being fragmented by brilliant-style faceting. At 16 x 13mm, the face-up coverage of this stone is extraordinary — commanding the full ring face with a deep, saturated violet-blue that photographs as intense purple in some lights and electric blue in others, and in person delivers a color experience that few other gemstones of any kind can equal.\u003c\/div\u003e","brand":"Gad \u0026 Co.","offers":[{"title":"Default Title","offer_id":47429617221822,"sku":"GA2203","price":19000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/5724\/6910\/files\/20_45-Carat-Emerald-Cut-Tanzanite-Diamond-in-14K-Two-Tone-Gold-Cocktail-Ring-Ring.jpg?v=1779352217","url":"https:\/\/assayjewelers.com\/ja\/products\/20-45-carat-emerald-cut-tanzanite-diamond-in-14k-two-tone-gold-cocktail-ring","provider":"ASSAY","version":"1.0","type":"link"}
