Vintage Round-Cut Amethyst Solitaire Ring

This piece is a vintage cocktail ring featuring a prominent round brilliant-cut amethyst gemstone. The amethyst displays a deep, saturated purple hue with visible flashes of violet and magenta, suggesting high-quality saturation. Measuring approximately 16.75 mm in diameter, the gemstone is held in an elevated four-prong setting, typical of Mid-Century or Retro-era jewelry (circa 1940s-1970s). The metal appears to be a warm-toned yellow or rose gold, which complements the deep purple of the stone. The ring size is documented as 5 3/4. Upon surface inspection, the crown facets of the amethyst show minor abrasions and edge wear consistent with its age and use as a decorative cocktail piece. The prongs appear thick and secure, though a professional jeweler's inspection of the metal under-gallery and shank for hallmark stamps (such as 14K or 18K) would be necessary for a full metallurgical valuation. The scale of the center stone relative to the band suggests a bold 'statement' design, valuing high-carat weight visibility over intricate metalwork. The transparency of the gemstone appears clear, lacking significant internal eye-visible inclusions that would detract from its brilliance.
