Norway is known for its lovely sterling and enamel jewelry. This is a cluster of three leaves, gracefully arranged. The leaves have an engine turned design and green enamel. This process is called guilloche' enamel. Pin is about 1 3/4" across and 2" top to bottom. It is in excellent condition with old patina. Pin has a safety clasp and is marked Sterling Norway. The patina can be polished away if you like. I don't polish vintage silver since many people like the patina to show.
