Southwestern band infinity band. Silver band features a blue/green turquoise and red coral triangle chip stone inlay design going all the way around the band. The ring is not marked and appears to be sterling silver (not marked as such, tested with a magnetic and did not attract, so not metal). Comparable rings are attributed to Navajo/Native American jewelry makers and it was common for these rings to be unsigned and unmarked pre-late 70s. Small ring size 4.5 - perfect for petite hands, pinky rings, or necklace charms.
