Channel set emerald green and crrystal clear rhinestones give this 10-sided Art Deco bangle the look of real emeralds and diamonds.  About 1/8" wide with an inside diameter of 2 7/8" - definitely designed for the larger wrist.  Silvertone metal, possibly stainless steel.  A couple of the clear stones have yellowed just the tiniest bit, overall condition is very good.
