Vintage Emerald-Cut Green Gemstone Yellow Gold Ring

This is a vintage cocktail ring featuring a large, rectangular emerald-cut gemstone of a pale green hue, potentially green amethyst (prasiolite) or a light-toned green synthetic spinel. The stone is securely housed in a multi-prong basket setting, likely crafted from 10k or 14k yellow gold, which shows a soft, warm patina consistent with age. Distinguishing features include a split-shoulder shank design with subtle decorative ribbing that tapers into a solid band. The gemstone displays notable clarity with visible internal facet reflections and minor surface abrasions on the table and crown facets, indicating regular wear. There are no immediate maker's marks visible in the photograph, but the construction style suggests a mid-20th-century origin, likely circa 1950s-1970s. The craftsmanship is solid, utilizing traditional prong-setting techniques common for the period. The ring is presented in its original or period-appropriate vintage jewelry box, which features a cream-colored textured lid and a gold-toned base, further supporting its vintage provenance. The overall condition appears good with expected minor metal scuffs and slight facet wear typical for a pre-owned estate piece.
