This dogwood brooch is hand formed from some kind of clay or china. These are highly glazed or coated. The petals are then outlined in what looks like copper wire. The center is an unglazed, rough mound of another material. The pin measures about 3 inches across and has a safety clasp on the back.
This looks to be old and has age crazing on the petals. This seems to be in the finish only and the pin is as stable as such a pin can be. Very pretty and a great piece for the dogwood collector.
