Eighteen round brilliant diamonds, G-H color and VS clarity, form a bright halo that frames the stone without competing with it. The 1970s mounting is a study in tactile craftsmanship, its 18k yellow gold and platinum shoulders worked in a fine ribbed, rope-like texture that wraps the finger in warm, dimensional metalwork — a hallmark of the era's more sculptural approach to gold. At 22.29 grams, this is a substantial, statement-making ring, sized 7 and resizable, presented in good condition. For a collector of important colored stones, a sapphire of this size and untreated pedigree rarely comes to market.\u003c\/div\u003e","brand":"Jack Weir \u0026 Sons","offers":[{"title":"Default Title","offer_id":49296762470619,"sku":"38493","price":17500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/1720\/files\/38493_4140462.jpg?v=1789166284","url":"https:\/\/jackweirandsons.com\/products\/vintage-gia-22-20-carat-burma-no-heat-sapphire-diamond-18k-gold-platinum-ring","provider":"Jack Weir \u0026 Sons","version":"1.0","type":"link"}
