A wonderfully complementary duo, this pair consists of a quite flexible choker with an inside opening of 4" across--when it's "at ease"! Should fit most necks when donned. The bracelet is also quite flexible and measures 1 3/4" at its highest point in front and has an inside opening of 2 1/2". Stones are glass-like but in actuality are plastic. Both pieces are in excellent vintage condition.
