The stone rises from a\u003c\/div\u003e\u003cdiv\u003edomed setting surrounded by an airy, pierced gold lattice, a construction technique that removes excess metal to let\u003c\/div\u003e\u003cdiv\u003elight move through the design and keeps a ring of this scale from feeling overly heavy. Twenty-six single cut\u003c\/div\u003e\u003cdiv\u003ediamonds, weighing approximately 0.60 carat in G-H color and VS clarity, are scattered evenly across that lattice\u003c\/div\u003e\u003cdiv\u003elike a scattering of stars, adding sparkle without ever competing with the sapphire's dominant color. Rendered in 18k\u003c\/div\u003e\u003cdiv\u003eyellow gold with platinum accents and hallmarked with French purity and maker's marks, the ring is sizable and\u003c\/div\u003e\u003cdiv\u003eweighs a substantial 23.17 grams. Circa 1940, this is a genuinely rare, one-of-a-kind statement ring, the kind of\u003c\/div\u003e\u003cdiv\u003edocumented, no-heat Sri Lankan sapphire that serious colored stone collectors search for over an entire career.\u003c\/div\u003e","brand":"Jack Weir \u0026 Sons","offers":[{"title":"Default Title","offer_id":49329375903963,"sku":"37919","price":35000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/1720\/files\/37919_4182291.jpg?v=1789771990","url":"https:\/\/jackweirandsons.com\/products\/french-retro-gia-17-92-carat-no-heat-sapphire-diamond-18k-yellow-gold-ring","provider":"Jack Weir \u0026 Sons","version":"1.0","type":"link"}
