Vintage Lapis Beaded Necklace

This lapis necklace is made up of round beads and flattened elongated beads. The length of the elongated beads is 1/2" and the round beads are 5mm. Very interesting gold plated toggle clasp. Measures 19" on length. On the third elongated bead from the straight part of the toggle there is what looks like a crack but this might just be the nature of lapis.
