This incredibly rare pendant is made of hand painted porcelain. It is set in a sterling (marked on the side) frame that opens at the back. I have seen these called vinaigrettes but I do believe this is a patch box. The silver has been gilded and has a light golden colour. The face is over 1 inch long not including the ring or bale, by 3/4 inch wide. The top ring is a replacement. Condition is very good.
