18K Gold Electroplated Cultured Pearl Bypass Ring

This item is a bypass-style fashion ring featuring a prominent spherical cultured pearl. The ring is constructed with a yellow gold-toned metal band. A critical physical characteristic of this piece is revealed by the internal stamping on the shank, which reads '18K G.E.', indicating that the item is 18-karat gold electroplated rather than solid gold. The 'G.E.' suffix is a standard marking for high-quality plating over a base metal, likely brass or nickel. The pearl possesses a creamy white luster with subtle iridescent overtones. Structurally, the ring appears to have a bypass or split-shank design that wraps around the center stone. Regarding condition, the image shows significant wear and oxidation. There is a noticeable greenish-blue tarnish or verdigris developing near the junction where the pearl is set, which is a common sign of the base metal corroding beneath the electroplating. The plating itself shows signs of thinning and surface scratches consistent with an estimated age of the late 20th century (circa 1970s-1980s). The craftsmanship is characteristic of mid-market costume jewelry, where aesthetic appeal is prioritized over intrinsic precious metal value.
