This vintage necklace is Lucite or a similar thermoplastic. It's first strand is 34 inches and the other, the larger bead is 32 inches. Lucite is suppose to float but I did not have the heart to get it wet. This lovely necklace is a lovely champagne color. It has a large insert closure in a plain gold-tone metal. This necklace is not for the timid, it is bold and massive and not as heavy as glass. It has a lovely way of laying againest the chest. The golden tone is perfect againest the color black. The longest strand is smallest 12mm bead and the center strand is almost twice as big. From Kansas lovely lovely Lucite necklace.
