1.5 Carat Round Brilliant Solitaire with Marquise Diamond Guard Suite

This jewelry suite consists of a central 1.5-carat round brilliant-cut solitaire diamond engagement ring paired with a two-piece interlocking or wrap-style ring guard. The central diamond is secured by a classic four-prong setting in a yellow gold mounting, likely 14k or 18k based on common period styles. The surrounding guard features a ballerina or starburst cluster arrangement consisting of approximately 14 to 16 marquise-cut diamonds, graduated in size to frame the central stone. The diamonds appear to be prong-set in yellow gold, create a distinctive 'halo' or 'sunburst' silhouette that was highly popular in the 1980s and early 1990s. The metal displays a warm yellow hue with a polished finish, though there is visible surface wear and minor scuffing on the bands consistent with long-term daily use. The central stone exhibits significant brilliance, though the clarity and color grade cannot be definitively determined without a loupe; visible inclusions or a slightly warm color tint may be present. The craftsmanship reflects a traditional multi-stone assembly, common in bridal sets from the late 20th century. Overall, the set is in good vintage condition with no major missing stones or visible prong failures, though a professional cleaning and prong tightening would be recommended for conservation.
