I believe this is an older Navajo piece and likely dating approximately to the 1960s–1970s, based on the large turquoise cabochon, hand-fabricated appearance, oxidized recessed background, sculptural silver overlay, and overall modernist design. The reverse is faintly stamped “STERLING,” confirming the pendant is sterling silver. The piece does not appear to carry a clearly identifiable artist hallmark, so the Navajo attribution and date remain informed observations based on style and construction.
