This three strand necklace is stunning. The small beads are black glass. They are graduated in length. The center beads are the focal point of the necklace. There are two round faceted beads, one red and one which is purple on one side and deep blue on the other side. The top bead is triangular in shape and clear like a giant diamond. I think the three large beads are glass but they could be lucite. I am just not sure. The top bead is about 1 1/2" x 1 1/4". The two round beads are about 1 1/8" across. Necklace is about 20 1/4" long along the shortest chain. It is signed Dauplaise on the clasp. The color seems to be a little uneven on the red bead but otherwise, necklace is in excellent condition.
