I hesitated to call this a brooch because it shows no evidence of ever having a pin attachment. I have seen another like this which has a wire frame to hold it like a small portrait. Whatever, the portrait is the famous Limoge 'Blue Girl' transfer with additional hand painted details. It is surrounded by tiny seed pearls (possibly faux) and set in a heavy gold-toned frame topped by a crown. The domed portrait approximately 1 1/2" tall, adding the frame it is 2 1/2" tall and approximately 2" wide. A beautiful piece.
