This unusual brooch is in excellent condition with an outstanding patina. There are ten circular forms around this piece depicting an acanthus design. What is interesting is the two curved pieces that protrude to the middle. I'm not quite sure the purpose of these but if you know, please email me. I'm also unsure which way is up!! This piece is 2" wide and 1 1/4" tall and weighs 5.6 grams of sterling. Marked sterling but no other mark. Very pretty.
