Lot of 4 garnet beaded necklaces different lengths and styles

4 garnet necklaces, 3 shorter single strand with various types of clasp/ closure and one longer 3 strand garnet necklace with a box closure and potentially gold or gold filled spacer beads and cultured pearl spacer beads. No marks other than a “12k” on the spring ring clasp of one single strand, which I presume denotes gold filled. The large pearl on the clasp of the larger necklace I do not believe to be cultured or natural in any way.
