Vintage Gold Bracelet with Marquise Emerald and Diamonds

This is a vintage-style yellow gold bracelet, likely 10k or 14k gold, featuring a central elongated lozenge-shaped decorative station. The centerpiece is set with a marquise-cut natural green emerald at its heart, surrounded by a halo of small, round-brilliant-cut diamonds or white accent stones. The central station is crafted with vertical fluted or ribbed gold details that taper as they meet the chain. The bracelet is attached to a flat curb or gourmette link chain. The construction appears to be high-quality cast jewelry with prong settings for the stones. The gold has a warm, bright polish with minimal surface scratching, indicating it has been well-maintained. There are no visible maker's marks or stamps in the current view, but the design style is reminiscent of mid-to-late 20th-century jewelry, possibly from the 1980s. The emerald shows natural inclusions typical of the gemstone, and the accent stones appears securely set. The overall condition is excellent with no signs of repaired links or loose stones.
