This wonderful estate find brooch is stamped sterling in 2 places and tests positive as sterling by using a safe, non-marking acid test. It has a curly C clasp that holds super well and has an early style hinge. I would put this piece somewhere in the Victorian to Art Nouveau eras. The repousse work is well done and the brooch has a beautiful aged patina. It measures approximately 1 3/4" x 2 1/2" and weighs 16.6 grams. Iy is in good vintage condition with normal age related surface and a lovely aged patina. I leave any polishing up to the buyer's discretion. Please ask any questions before bidding. Thanks for visiting!
