Masonic Black Onyx and Diamond Ring in Yellow Gold

This is a men's fraternal signet-style ring featuring the iconic Square and Compasses emblem of Freemasonry. The ring is constructed with a substantial yellow gold band, likely 10k or 14k, showcasing a rectangular polished black onyx tablet as the central focal point. Inset into the onyx is a white gold or silver-toned Masonic emblem, which is adorned with a small round-cut diamond at its center. The shoulders of the ring are intricately designed with a tiered, architectural motif and are accented by two additional small melee diamonds set in light-colored metal. The craftsmanship indicates a mid-20th century construction (circa 1950s-1970s), characterized by its bold, masculine proportions and high-relief detailing. The gold shows signs of natural wear with minor surface abrasions and a slight patina consistent with long-term use. The onyx appears to be in good condition without visible chips on the top surface. The diamonds are securely set, and the overall structural integrity of the shank remains robust. Quality indicators include the precise mounting of the emblem onto the stone and the balanced symmetry of the side accents.
