Here is a great clear lucite necklace probably from the 1960's or 70's. In between each lucite cube is a brass colored plastic matte bead. The largest center cube measures 1" square and the smaller cubes 1/2" square. The length is 25.25". It has a spring ring closure that may need to be replaced as it has lost its spring mechanism. It can always be pushed to the closed position. There is a tiny silver loop that does not go with the necklace but I don't have a tool to take it off. I don't see any chips on any of the cubes. It is quite light weight in spite of the large pieces that make it up.
