Turquoise necklace

Turquoise stone beaded necklace. Beads are speckled and have a porous, natural finish, they feel like they’re made out of stone. Accented with a few silver beads. Hook & eye closure. One bead looks like it has a crack, or it could be natural (I honestly can’t remember), this is hardly noticeable. Measures 18” from end to end.
