This vintage Tiffany & Co. cabochon amethyst ring is crafted in 18k yellow gold and stamped Tiffany & Co., 750, Italy. Dating to the 1980s, the design features a smooth, polished band set with an oval cabochon-cut amethyst at the center. The amethyst displays its natural translucence and internal inclusions, characteristic of cabochon cutting, which highlights the stone’s depth of color rather than brilliance. The band measures 3/8” in width and the ring weighs 8.17 grams. It is a size 6.5 and can be resized. The interior hallmarks confirm Italian manufacture for Tiffany & Co. This piece shows surface imperfections consistent with age and wear, adding to its authenticity as a vintage design.
