Vintage black and pale blue glass berry beaded charm necklace, gold tone wire spiral cages and filigree bead caps

Fabulous vintage black and pale turquoise blue beaded necklace in gold tone, with gold tone wiring and bead caps. It has three glass bead drops which are encased in gold tone wire spiralling round each bead. The black and turquoise beads around the neck are alternated in an asymmetric harlequin pattern. This piece is really nicely finished and has a good weight to it - it reminds me of pieces by Miriam Haskell and is so unusual. It has a length of about 17 inches and fastens with a secure spring ring clasp. The necklace is in very good vintage condition.
