Hello Florence,
This appears to be a necklace composed from Central European beads, probably Czech. The oval white beads are molded; the teal beads appear to have lampworked crumb decoration imitating turquoise in matrix; and the fluted brass beads—all are typical of Czech production.
Be well. Jamey
Thanks, Jamey. They look Czech to me, probably c. 1930's.
Regards, Florence
