These millefiori or "ice house" glass beads were made by melting and hand-twisting glass rods. Perhaps the "ice house" nickname is because the patterns are so cool.
Each necklace has a metal clasp, except as noted. Length is approx. 18" to 22". Beads are approx. 1 to 2.5 cm in length by 1 cm in dia.; some beads are smaller (e.g. amber-colored), see photos.
These necklaces come in amber-colored (21", 22"), black (19", 21"), black with red (22", smaller beads, tied clasp); blue (18", 19"), green (21"), orange (21"), and pink (21", 22"); with multi-colored accents.
