This exquisite Tiffany & Co. ring exemplifies timeless elegance in 18k yellow gold. Featuring fifteen round-cut diamonds meticulously prong-set in the iconic Signature X design, this retired piece showcases exceptional craftsmanship. The substantial 9.14mm top width tapers gracefully to a refined 2.35mm band, creating a striking silhouette. Originally retailing at $3,500, this signed estate treasure offers a rare opportunity to own a coveted design no longer in production. Currently sized at 5.75 and available for resizing, it weighs 3.80 dwt and represents a sophisticated investment in fine jewelry heritage.
