Men's Vintage Yellow Gold Sapphire Signet Ring

This is a men’s signet-style ring featuring a prominent round faceted blue sapphire. The central gemstone is a deep navy blue hue, possibly a natural or lab-created sapphire, estimated at approximately 2.0 to 2.5 carats. The stone is securely set within a recessed square-shaped white metal illusion plate, likely platinum or white gold, which enhances the visual diameter of the gem. The primary band is constructed from yellow gold, which displays a warm, aged patina. The shoulders of the ring feature a distinctive fluted or 'scalloped' ribbed design that adds significant texture and a mid-century aesthetic. The construction appears heavy and masculine, typical of jewelry styles from the 1940s to the 1960s. Regarding condition, there is visible surface wear including fine scratches and minor abrasions consistent with regular use. No maker's marks or gold assay stamps are clearly visible in the image, though the style suggests high-quality commercial craftsmanship. The ring's substantial width and geometric lines are characteristic of late Art Deco or retro-modern design influences.
