Modernist Gold and Diamond Cocktail Ring

This is an elaborate cocktail ring, likely crafted from 18k yellow gold, given the rich hue indicated by the '18k' context. The design features a bold, sculptural form with a substantial gold weight. The most prominent feature is a marquise-cut or elongated oval-cut central diamond, bezel-set in a smooth, polished gold setting that extends perpendicularly from the main body of the ring. This central stone appears to have some warmth in its color, possibly a faint yellow or champagne tone, and shows good brilliance. Flanking this central element, the main body of the ring is a broad, curved, and tapered band that is lavishly embellished with numerous pavé-set round brilliant-cut diamonds. These smaller diamonds are tightly packed, creating a sparkling, textured surface over a significant portion of the ring's design, suggesting a 'bling' factor typical of cocktail rings. The surface not covered by diamonds exhibits a smooth, high-polish finish, contrasting with the textured diamond-set areas. There are no visible maker's marks or signatures in the provided image, but the overall presentation suggests a well-crafted piece. The ring appears to be in good condition with a visible patina consistent with age and wear on the gold surfaces, and all stones appear to be intact. The style suggests a mid-to-late 20th century, possibly 1970s or 1980s, modernist aesthetic, characterized by organic shapes and a substantial gold presence. Its construction speaks to quality craftsmanship, designed to make a statement.
