Two round brilliant cut diamonds, weighing approximately 0.30 carat in G-H color and VS clarity, flank the sapphire in a simple three-stone format that keeps the focus squarely on the center stone's natural color and considerable size. Crafted in 14k yellow and white gold and hallmarked with a purity mark, the ring weighs 4.36 grams, a comfortable, well-proportioned weight for everyday wear. Circa 1980s, this is a genuine find for a colored-stone collector, pairing real rarity, a documented no-heat pink sapphire of this scale, with an approachable, wearable three-stone design rather than an elaborate or fragile setting.\u003c\/div\u003e","brand":"Jack Weir \u0026 Sons","offers":[{"title":"Default Title","offer_id":50557908615387,"sku":"38761","price":7500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/1720\/files\/38761_4250757.jpg?v=1790981897","url":"https:\/\/jackweirandsons.com\/products\/vintage-gia-3-72-carats-no-heat-pink-sapphire-diamond-14k-yellow-gold-ring","provider":"Jack Weir \u0026 Sons","version":"1.0","type":"link"}
