Vintage Czech Blue glass cube beads long flapper necklace from the 1920's

This is a beautiful vintage Art Deco, Czech glass, chunky cube beads flapper necklace. The cubes are cornflower/sapphire/cobalt blue. The cubes get smaller as they go towards the neck area. Cubes are threaded on string with each bead/cube being hand knotted. There are pressed glass spacer beads in between each cube. There is no clasp but it is very easy to pull over your head. The approximate measurement of the necklace is 50 inches long. In good condition. This is a rare find. A portion of the proceeds goes to various charities. Thank you for shopping!
