This is a vintage 1920-1930s Bohemian Czech glass bead string from a group acquired from a fellow jeweler in his 90s, who bought a number of strands in the 1930s for use as parts.
The necklace measures 17 inches long, and is strung on string.

There are black glass tube beads, turquoise blue round beads and iridescent pink tube beads.

 The necklace is one of the 5 original strands I had, but doesn't have the old paper tag for Czechoslovakia that the others do, and was constructed differently than the others, as this is without a catch, and is double strung.

I have included a photo of the paper tag from another strand, but this one no longer has one, as seen in the other photos.

 Wonderful for a colorful necklace alone or for use in so many jewelry and craft projects needing vintage glass beads.
