This fantastic necklace is featured in Roseann Ettinger's book "Popular Jewelry of the '60, '70's and 80's" A necklace similar to this one (but not as spectacular) can be found on p. 66. The author says it is made with "...large plastic beads resembling butterscotch amber..." The necklace shown in the book has only one of the large beads and this one has three. This necklace is about 35" long. It does not have a clasp. You just slip it on. It is a great reminder of the fabulous 1960's and will give you many years of wearing pleasure. Necklace is in excellent condition.
