Delightful, French silver brooch commemorating Francis I, the Salamander King. The piece bears the French boar's head hallmark under the trombone clasp. I believe this mark indicates it is 800-900 silver. It does test positive for silver content. I would date this piece to the late 19th century.
The brooch is 1 and 7/16 x 1 and 5/16 inches and it weighs 8.5 grams.
Very good condition with a heavy, even, patina.
