Pair of genuine freshwater pearl necklaces, one signed

A great pair of necklaces, both about 16 inches long. The all-pearl necklace has a gold filled clasp, with the triangular mark of Grassman-Blake, an American company that's been in business for 75 years. The second necklace is strung with glass seed beads and freshwater pearls with metal spacers and has a fused glass pendant. It has a toggle closure. The all-pearl necklace is marked 1/20 12K GF, while the other has no markings. Both in great shape.
