Vintage Fresh Water Pearl Memory Wire Bracelet 3 Strand

Older unmarked bracelet. These are fresh water pearls - rice pearls. Memory wire style. Can stretch to fit a few wrist sizes. Real fresh water pearls, gold-tone beads, black beads are glass or stone? Gold-tone beads are not real gold. I think they are a brass. Approx size 6.5”-7” White to off white colored pearls.
