This is one of my favorite designs by Kunio Matsumoto. It is industrial with the clever use of metal and unforgettable with the mix of Lucite and different beads. The centerpiece is metal on one side and a translucent Lucite with metal bands on the other. The chain has a mix of white and clear Lucite beads. The center is 4 3/4" across the top edge and 1 1/8" at the widest part. The white beads near the center are about 15.5mm. Note the silvertone spacers which tie it in with the center. Necklace is about 18 1/4" long and has its original tag so I doubt that it was ever worn. It is in excellent, like-new condition.
