Czech Dark Blue Glass Beaded Slip Over Necklace. Not marked but undoubtedly Czech. Fabulous workmanship on the goldtone beads and openwork metal designs. Each bead is separately knotted between. No clasp, just slips over the head. I can just see a flapper dancing with this stunning piece around her neck. 27" long with the large blue glass stone mounted in the filigree pendant adding another 4". No damage.
