Four further Old European cut diamonds, weighing approximately 0.20 carat in G-H color and VS-SI clarity, flank the center stone, while four round cut synthetic rubies, weighing approximately 0.30 carat, add warm red accents, a lab-created stone choice that was common and openly used in fine Retro-era jewelry rather than a later substitution. Crafted in 18k rose gold and platinum and hallmarked with an engraved weight mark, the ring weighs 9.53 grams and carries the bold, geometric tank-ring silhouette the era was known for. Circa 1940s, this is a striking example of Retro design, combining a genuine diamond center with the period's characteristic use of synthetic color stones as accents.\u003c\/div\u003e","brand":"Jack Weir \u0026 Sons","offers":[{"title":"Default Title","offer_id":50518186524891,"sku":"39012","price":8800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/1720\/files\/39012_4196183.jpg?v=1790375181","url":"https:\/\/jackweirandsons.com\/fr\/products\/retro-1-47-carat-diamond-synthetic-ruby-18k-rose-gold-platinum-tank-ring","provider":"Jack Weir \u0026 Sons","version":"1.0","type":"link"}
