Vintage 10K Yellow Gold and Simulated Ruby Men's Signet Style Ring

This is a men's signet-style ring crafted in yellow gold, featuring a prominent rectangular synthetic or simulated ruby. The ring's band is constructed with a wide, tapered shank that broadens toward the shoulders to accommodate the head. Visible on the interior of the shank is a '10K' hallmark, indicating the gold purity is 10 karats. The gemstone is a vibrant, saturated pinkish-red hue with a step-cut or rectangular emerald-cut facet pattern, securely held in a bezel or heavy flush setting typical of mid-20th-century masculine jewelry design. The metal displays a polished finish with moderate surface scratches and small dings consistent with regular wear and age (estimated mid to late 20th century). While the stone appears intact, there is minor abrading on the facet junctions visible under close inspection. The craftsmanship is solid but mass-produced, lacking high-end hand-engraving, which suggests an accessible commercial origin. The overall condition is good, showing no structural repairs but significant patina and wear to the gold's surface.
