Men's Cushion-Cut Blue Gemstone Signet Ring

This is a men's signet-style ring featuring a prominent cushion-cut blue gemstone, likely sapphire, tanzanite, or a synthetic equivalent, set in a bezel or semi-flush mounting. The metal appears to be polished yellow or white gold (visibility is slightly obscured by lighting), exhibiting a wide, substantial shank that tapers toward the back. The gemstone displays a deep, rich cobalt blue hue with visible facets that catch the light, suggesting a transparent or translucent quality. The construction is solid and heavy, indicative of mid-to-late 20th-century jewelry design, possibly late 1980s or 1990s. The ring shows minor surface scuffs and light patina consistent with regular wear, though no significant structural damage or stone chips are immediately visible from this angle. Detailed maker's marks or metal fineness stamps are likely located on the inner band. The craftsmanship appears to be of high quality, with a smooth transition between the setting and the stone, typical of professional bench jeweler work meant for durability and masculine aesthetic.
