This vintage Cartier diamond band ring, crafted in 1993, is made of 18k yellow gold and features a minimalist design. The central round brilliant-cut diamond is set flush within the band, providing a sleek and secure look. The band itself measures 1/4 inch in width and exhibits a natural patina that adds character to its vintage appeal. Weighing 12.4 grams, this ring is a size 6.5 and combines elegance with everyday wearability. The interior of the band is stamped with “Cartier, 750, 1993, 53 43 EC 0.45,” and also a maker's mark, attesting to its authenticity and the diamond's weight of 0.45 carats. This timeless piece is a perfect example of Cartier’s understated sophistication.
