During the Art Deco period the bakelite inventors found a way to make bakelite that was transparent and christened it "Prystal". It mimics amber. This garnet red version known as "Cherry amber" has great gem like clarity and glow. These necklaces are so good that they are often mistaken for real amber but don't get fooled! But these bakelite prystal necklaces are the jewel in the crown of the bakelite world. The middle largest bead measures 1" long and 18mm wide! The barrel shape beads graduate to the back and there is a screw top closure, on perfect shape. The graduation of the beads and geometric facetted machine craft of this piece identify it as a Deco piece. The whole necklace is hand knotted also in perfect shape and very secure. The length is 31" long. A thing of beauty is a joy forever and this Art Deco prystal necklace qualifies.
