Large Amethyst and Gold Cocktail Ring

The item is a large cocktail ring featuring a prominent rectangular or emerald-cut gemstone, likely amethyst given its distinct purplish hue. The stone is set in a substantial yellow gold mounting. The gold setting appears to be an open-work or filigree design with flowing, sculptural lines that embrace the stone, rather than a simple bezel or prong setting. This elaborate work on the shoulders of the ring gives it an Art Nouveau or Mid-Century Modern aesthetic, suggesting it could be from the early to mid-20th century. The gold has a polished finish and shows no visible signs of significant wear such as scratches or tarnishing in the image. There are no obvious chips or cracks visible on the gemstone itself, which appears to be translucent with consistent coloration. The sheer size of both the stone and the setting indicate it is intended as a statement or 'cocktail' ring. Due to the angle, maker's marks or other internal stamps are not discernible. The craftsmanship appears to be of good quality, with well-formed metalwork and a securely set stone, indicative of a professionally made piece of jewelry.
