Vintage Navajo Bench beads sterling silver turquoise coral bone? Necklace

Space on string as seen in photos Needs restrung vintage Native American-style necklace featuring various materials including silver-tone "bench" beads, turquoise, and what appears to be bone or shell, possibly originating from the Navajo or Santo Domingo Pueblo people. The beads are strung together in a style that is often referred to as Heishi, which traditionally means shell bead, but the term now encompasses other materials. Key Features Beads: The necklace incorporates several types of beads: Silver-tone beads: These appear to be hollow, bench-made beads, a common feature in Southwestern jewelry. Turquoise: Natural, freeform turquoise nuggets and a prominent, elongated central turquoise bead add vibrant blue-green color. Natural Materials: Smooth, polished barrel-shaped beads of a brownish material appear to be bone or perhaps a type of shell, like clam or pen shell. Coral accents: Small red coral pieces are visible near the clasp and at the center of the necklace. Style: The use of multiple natural materials and hand-formed beads is characteristic of traditional Native American, specifically Navajo or Kewa Pueblo (Santo Domingo), craftsmanship.
