This vintage Cartier marquise cluster ring, crafted in 18k yellow gold, features a bold pave diamond design. The marquise-shaped center is fully set with round brilliant-cut diamonds, with additional diamonds along the shoulders for continuous sparkle and dimension. The ring weighs 4.2 grams and is a size 6.5. It is stamped “Cartier,” “53” (European ring size), “750” for gold purity, and carries a unique serial number. Circa 1980s, this ring reflects Cartier’s elegant craftsmanship from that era. There is a light patina on the gold consistent with age, adding to the character of this vintage piece.
