United States Military Style Commemorative Ring

This is a gold-tone, bulky signet-style class ring or service ring, likely commemorating service in the United States military. The ring features a large, faceted oval blue stone (possibly synthetic sapphire or blue glass) set within a central bezel. Surrounding the center stone are the words 'UNITED STATES' embossed in uppercase block lettering against a textured, darkened background. The shoulders of the ring are intricately decorated with relief carvings; one side appears to feature an American Eagle with outstretched wings, a common motif in US military jewelry. The construction appears to be a heavy base metal with a yellow gold plating or coating. Condition-wise, the ring shows significant signs of wear and age. There is noticeable loss of the gold plating on high-friction areas such as the rim of the bezel and the raised edges of the shank, revealing a darker or duller base metal underneath. The stone appears to have some surface griminess or minor abrasions, and there is a heavy patina or buildup of dirt/oxidation in the deep recesses of the casting. These types of rings were frequently mass-produced from the mid-to-late 20th century onwards as souvenirs or commemorative items rather than official government-issued insignia. No specific maker's mark or metal purity stamp (such as 10k or 14k) is visible from this angle, and the high level of plating wear suggests it is costume jewelry rather than solid gold.
