Vintage Art Deco bright blue, white, black and silver foiled glass beaded necklace, beautiful beads

Vintage Art Deco necklace with beautiful blue, white, black and silver foiled glass beads with smaller dark blue glass spacer beads. Each luminescent glass bead contains a beautiful foiled texture with shades of blue and silver inclusions. I understand this type of bead comes under the Murano glass category from Italy and are hand-crafted. This textured foil effect with the metallic glow I have heard called 'lava' beads. Any bead experts out there, do message me and correct me if I am wrong!

These beads are lovely examples and the necklace fastens with a secure silver tone spring ring clasp. It has a length of about 17 inches and is in very good vintage condition.
