1930's Long Spiral Beads

Brilliant blue beads mimicking a lapis lazuli color. Slide clasp with circular beading to accent. Interesting spiral 'DNA" style twisting, very long. I thought this piece might be mid-century but the very long style denotes the wrap around of swinging lariat styles of the deco eras. I am unsure what the beads are made of, lightweight.
