Large Round Faceted Amethyst or Alexandrite Cocktail Ring in Yellow Gold

This is a statement cocktail ring featuring a very large, round brilliant-cut gemstone. The stone exhibits a deep purple to pinkish-lavender hue, characteristic of amethyst or synthetic color-change alexandrite, which was common in mid-20th-century jewelry. The gemstone is held in an open-back yellow gold setting with eight substantial prongs securing the girdle. The band (shank) features a distinctive split or triple-wire design that tapers as it moves away from the head of the ring, a style often associated with Retro or mid-century modern eras (circa 1940s-1960s). The craftsmanship appears sturdy but utilitarian, typical of commercial fine jewelry from the mid-century period. Regarding condition, the metal shows minor surface scratches consistent with age and light wear. There is visible lint and dust on the stone and settling in the black velvet display box, which suggests the piece has been stored for some time. No significant chips or fractures are immediately visible on the crown facets, though a professional cleaning and loupe inspection would be required to confirm the integrity of the facet junctions and the girdle. There are no visible maker's marks or hallmarks from this angle, though they likely reside on the inner shank.
