Vintage 14K Yellow Gold Ruby and Diamond Cluster Cocktail Ring

This is a vintage cocktail ring crafted in yellow gold, likely 14K or 18K purity based on the deep tonal hue. The piece features a distinctive 'butterfly' or 'twin-fan' bypass design. Each side of the bypass terminal is set with a floral cluster consisting of a central round-cut clear stone (likely a small diamond) surrounded by six small round-cut red gemstones, which appear to be natural rubies. The metalwork displays high-level craftsmanship, featuring a wide shank with decorative openwork geometric cutouts (star and cross patterns) along the shoulders. The settings for the stones are mounted on scalloped, fan-shaped plates with fine engraved radial lines for texture. The overall aesthetic suggests the Mid-Century Modern or Retro period, approximately 1940s-1960s. Regarding condition, the metal shows minor surface abrasions and a softened patina consistent with regular wear. All gemstones appear securely prong-set, though some dirt buildup is visible behind the cluster settings which can be addressed with professional cleaning. No visible hallmark is seen in the photo, though such marks are typically located on the interior of the lower shank.
