This ivory bead necklace is vintage circa 1930s. The beads are oval shaped and graduate from about 7mm to 15mm in size. The ivory has darkened over the years and it is more evident on some of the beads than others and a few of the beads have some crazing. The clasp is the type that screws on and off. The necklace is 16 inches in length. This is a wonderful vintage piece but if you prefer white ivory, evenly colored, this piece is not for you.
