Tulum GIA 1.55 carat diamond 18k gold platinum engagement ring

Four platinum claws hold a long cushion brilliant cut diamond above a slender, warm-toned band, the stone seeming to float with almost nothing between it and the light. Certified by GIA, the center diamond weighs 1.55 carats in I color and I1 clarity. Look at the ring from the side and a ring of tiny diamonds is visible beneath the stone, a hidden halo that adds a fine sparkle from every angle; sixteen round brilliant cut diamonds, approximately 0.20 carat in total in G-H color and VS clarity, accent the setting. The cushion cut, with its softly rounded corners, gives a slightly more romantic look than a crisp rectangle. Crafted in 18k gold and platinum and stamped with a purity mark, the ring weighs 4.00 grams. Circa 2026, it is a clean, contemporary solitaire for someone who wants a slim, classic engagement ring that quietly reveals extra sparkle only when seen up close, and who values a large center stone worn low and light on the hand.
