United States Military Commemorative Ring

This is a yellow gold-toned commemorative ring, likely representing a branch of the United States Armed Forces, specifically the Navy or Air Force given the choice of stone. The ring features a large, cushion-cut synthetic blue spinel or sapphire center stone held in a bezel setting. Surrounding the stone is a dark blue or black enamel halo featuring the raised gold lettering 'UNITED STATES'. The shoulders of the ring are heavily embossed with symbolic military iconography, though the specific branch insignia is slightly obscured by the angle. The construction is reminiscent of mid-to-late 20th-century class ring styles, characterized by a heavy, solid shank and cast details. The metal shows significant surface scratches, minor pitting, and wear consistent with regular use, particularly around the edges of the bezel and the lower shank. The plating shows slight thinning in high-friction areas, suggesting it may be gold-plated brass or a similar alloy (such as Valadium or Celestrium) rather than solid high-karat gold. There is a visible patina and light oxidation in the recessed areas of the textured shoulders. No specific maker's mark or metal purity stamp is visible from the top view, but the overall craftsmanship is consistent with established commemorative jewelry manufacturers like Jostens or Balfour.
