In the center is 2.8mm Diamond and to each side are tiny French Cut Emeralds. The brooch is in excellent condition with the clasp working properly. There is one of the tiny Emeralds missing from the channel setting. Very difficult to notice without close scrutiny and could be replaced by a jeweler. The other 4 stones in the channel are tight. It measures 2-1/8" long, 3/4" at its widest and weighs 4.5 grams. Tested for accuracy. Not a reproduction, simply beautiful. I'll be adding better photos soon.
