Vintage/Antique Signet Ring with Inlay

The item appears to be a vintage or antique signet ring, crafted from a metallic material that exhibits a golden hue, suggesting it could be gold, gold-filled, or brass. The ring features a broad, flat face, characteristic of signet rings, mounted with a rectangular or slightly trapezoidal cabochon stone or inlay. This central element is light-colored, possibly white, cream, or a very pale ivory, which could be mother-of-pearl, an opaque gemstone like chalcedony, or even a synthetic material. Upon this light-colored surface, there is a dark, possibly engraved or applied, symbol or initial. While not perfectly clear due to image resolution, it seems to be a single, stylized letter, potentially an 'A', 'B', or similar. The shoulders of the ring, where the band meets the central setting, are textured with horizontal ridges or fluting, adding a decorative element. The band itself is a simple, polished oval. The overall condition appears to be good with some visible wear consistent with age and use, such as minor surface scratches and possibly some loss of original finish or patina on the metal. There are no obvious signs of significant damage, repairs, or missing components. The craftsmanship suggests a mass-produced item rather than bespoke, but still possesses a certain quality, typical of class rings or fraternal organization jewelry from the mid-20th century.
