Round Brilliant Cut Diamond Solitaire Engagement Ring

This item is a classic Tiffany-style solitaire engagement ring featuring a single round brilliant cut diamond. The central gemstone is approximately 0.50 to 0.75 carats, set in a traditional four-prong white gold or platinum head to ensure maximum light performance and security. The band or shank is crafted from polished yellow gold (likely 14k or 18k), exhibiting a sleek, rounded profile that tapers slightly as it meets the setting. The contrast between the white metal setting and the yellow metal band is a common mid-to-late 20th-century design choice, intended to enhance the diamond's colorlessness. The diamond itself appears to have good brilliance and fire, suggesting a well-proportioned cut. From the visual inspection, the ring shows minor surface wear consistent with regular use, including faint scratches on the gold shank and a light patina. The prongs appear intact, though a professional jeweler's inspection would be needed to confirm the security of the stone. No specific maker's marks or hallmark stamps are visible from this angle, but the overall craftsmanship indicates a high-quality commercial or boutique jewelry origin. This style is timeless, quintessential of 20th-century bridal fashion.
