Vintage Millefiori glass bead necklace. This necklace is composed of black glass beads that have mixed color designs on them. These beads are different shapes and sizes but all of them look amazing. These pieces are strung onto a clear nylon string which holds very well and some contain silver filigree metal caps that really sparkle. Some of these glass beads are spaced with one to four clear glass spacers as well. The beads range in sizes from 9mm long by 8mm wide to the largest being 21mm long by 10mm wide. These beads contain mixed colors that are known as millefiori. These colors make up swirled designs and floral motifs out of blue, red, green, yellow, and white hues that look brilliant. This necklace is fastened with a hook style clasp that connects to gold tone metal rings and the entire necklace measures 19 1/4" in length. A millefiori on black glass bead necklace.
