I don't think this is a JAR piece--it is not naturalistic in his manner. To me the multicolored gold looks reminiscent of 1940s jewelry, though this brooch may be later. Like many jewels of the forties, it has strong stiff lines and is almost garish to present taste. I thought it looked rather wonderful from a distance, making a splashy statement on the white fabric. The dots on the dress are embroidered in metallic thread of varying gold, bronze, and silver hues that set off the colors of the brooch too.
