Vintage 2 Strand Chunky Red Pink Swirl Graduated Lucite Acrylic Bead Necklace

Vintage two strand red and pink swirl graduated bead necklace. I'm not sure if this is lucite, acrylic or some other type of material. What I know for certain is the colors are pretty terrific especially for this time of year. Approximate measurements. Necklace: The length of each strand is difficult to measure; the shorter one is approximately 16-1/2" long and the other one is about 17-3/4" long. Beads: The five largest beads are 29mm x 22mm. There are 21 beads 12mm x 12mm 5 are 9mm x 7mm, 2 20mm x 16mm, 8 at 6mm, 5 at 8mm and 10 at 12mm. Excellent condition.
