Judging by the clasp on this necklace, this is a really old double strand of beads. They are 13 inches (the shortest strand) plus an extender of 3½ inches. The beads are a mix of dimpled turquoise with a slightly metallic tinge, clear lucite or plastic beads and spacers of faceted clear lucite beads. The metal bars at the clasp have 5 stars on them. Those stars are the only possible clue to the manufacturer.
