Vintage 14k Yellow Gold and Diamond Men's Signet-Style Ring

This is a substantial men's cocktail or signet-style ring crafted in what appears to be 14k or 18k yellow gold. The ring features a distinct bypass or split-shoulder design that converges towards a central diamond-shaped head. The primary setting is a white metal plate—likely white gold or platinum—arranged in a rhombic shape to enhance the brilliance of the stones. At the center is a larger round brilliant-cut diamond, surrounded by four smaller accent diamonds set at the corners, creating a 'starburst' or cluster effect. The gold shank has a soft, matte or brushed satin finish on the outer edges, providing a refined contrast to the polished elements. The style is characteristic of mid-to-late 20th-century jewelry design, approximately 1970s to 1980s. Physically, the shank appears robust and carries a significant weight. The stones show good clarity from a distance, though a professional cleaning is needed to remove surface oils. Regarding condition, there is a visible aged patina and minor surface abrasions consistent with regular wear. No obvious hallmarks are visible in the photograph, but the construction suggests professional bench-work. The item is presented in a red velvet-lined presentation box, which indicates it has been kept as a significant personal piece.
