Tiffany & Co. 18k Gold Amethyst and Diamond Cocktail Ring

This is a high-jewelry cocktail ring featuring a substantial central oval-cut amethyst weighing approximately 9 carats. The amethyst exhibits a deep, vibrant royal purple saturation with excellent internal transparency. It is securely prong-set within a textured 18k yellow gold mounting. Flanking the central stone are 12 round-brilliant diamonds totaling approximately 1.5 carats, arranged in cluster formations on the shoulders to enhance the ring's brilliance. The gold work features a distinctive scalloped or 'sunburst' textured border surrounding the amethyst, characteristic of Mid-Century to Retro-style designs often produced by Tiffany & Co. during the mid-20th century. The ring has an approximate total metal weight of 16.6 grams, indicating a heavy, solid construction of high quality. While the image is slightly soft, the stones appear well-set with no visible chips or fractures. The metal shows a gentle patina consistent with a well-maintained vintage piece. It is housed in a professional black velvet display case, underscoring its luxury status.
