This is a sterling silver band ring featuring a repeating geometric engraved pattern around the exterior.
The ring shows a patina consistent with age and apparent wear, giving it a slightly tarnished finish. Hallmarks inside the band are faint but indicate a silver composition. The design presents cleanly incised motifs, evenly spaced for a uniform appearance. This unisex accessory is suitable as a standalone piece or as part of a stack.
Based on the provided photos, the ring size appears to be approximately 16 mm in diameter (see ring mandrel photo). See photos for measurements, if taken.
