Solitaire Engagement Ring in Gold Mine Sales Presentation Box

This item is a solitaire gemstone ring, likely an engagement ring, displayed inside a vintage red leatherette or textured paper presentation box. The ring features a split-shoulder shank design that tapers toward a central four-prong or six-prong setting. The metal of the band appears to have significant tarnishing or a dark patina, which may indicate it is silver-based or a low-karat white gold that has lost its rhodium plating. The central stone is approximately 0.25 to 0.50 carats, though clarity and exact type cannot be determined through the image. The box lid interior features a gold foil stamp from 'GOLD MINE SALES' located in Spring Valley, New York, including a diamond silhouette logo and a 914 area code telephone number. This suggests the piece likely dates from the late 20th century, specifically the 1980s or 1990s based on the typography and box style. The condition of the ring shows visible oxidation, while the box shows minor wear along the hinges and edges but remains structurally sound with a clean white satin and velvet interior.
