Mystic Topaz Pendant on Omega Chain Necklace

This jewelry piece consists of a trillion-cut mystic topaz pendant suspended from a yellow gold omega chain. The necklace features a rigid, semi-flexible 'omega' style construction, which is characteristic of contemporary jewelry design from the late 20th century. The metal displays a bright, high-polish yellow finish, suggesting it is either 14k gold or a high-quality gold plating. The omega chain appears uniform in width and maintains a consistent, rounded profile designed to sit flat against the neckline. The central pendant features a fan or trillion-cut gemstone, identifiable as 'Mystic Topaz' due to its distinct iridescent, rainbow-like color shifts of purple, green, and blue. This effect is achieved through a thin-film chemical vapor deposition (CVD) coating on natural colorless topaz. The gemstone is securely held by a modified 'V' prong setting with a integrated polished bail that slides freely along the chain. The overall condition appears excellent with no visible tarnishing or significant scratches on the metal, and the gemstone's coating remains vibrant and intact across its table and facets. The craftsmanship indicates a commercial-grade fine jewelry piece, likely manufactured between the late 1990s and the 2010s, a period when mystic topaz was highly popular in the consumer market.
