{"product_id":"tulum-gia-1-55-carat-old-mine-cut-diamond-18k-yellow-gold-platinum-ring","title":"Tulum GIA 1.55 carat old mine cut diamond 18k yellow gold platinum ring - T\u0026H Exclusive","description":"\u003cdiv\u003eAn old mine brilliant cut diamond, weighing 1.55 carats and certified by GIA in F color and SI2 clarity, anchors this engagement ring with the deep pavilion and soft, candlelit sparkle that defines pre-modern diamond cutting, a cut choice made deliberately here rather than inherited from an actual period piece. Twelve round brilliant cut diamonds, weighing 0.10 carat combined in G-H color and VS clarity, run along both shoulders in a bright, continuous row, extending the sparkle outward from the center stone rather than leaving the band bare. Crafted in 18k yellow gold and platinum and hallmarked with a purity mark, the ring weighs 3.93 grams, well-balanced and comfortable for daily wear. Made new in 2026, the combination of an old mine cut center diamond with fully diamond-set modern shoulders gives this ring a foot in both eras at once, romantic in its cut and thoroughly contemporary in its construction and documentation. A thoughtful choice for anyone who loves the warmth of antique-style cutting but wants the fuller shoulder sparkle and GIA-certified reassurance of a brand-new engagement ring rather than an estate piece.\u003c\/div\u003e","brand":"Trumpet \u0026 Horn","offers":[{"title":"Default Title","offer_id":67641323848002,"sku":"37378","price":14500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2428\/9807\/files\/37378_4250681.jpg?v=1790985263","url":"https:\/\/trumpetandhorn.com\/products\/tulum-gia-1-55-carat-old-mine-cut-diamond-18k-yellow-gold-platinum-ring","provider":"Trumpet \u0026 Horn","version":"1.0","type":"link"}
