This is a large antique Victorian sterling silver and guilloche enamel brooch. The brooch has a C clasp and a tube hinge pin. It is signed Sterling and has an H in a triangle mark that I am not familiar with. The brooch has a pair of oranges and leaves on either end. The brooch measures 3-1/8 inches by 1-3/4 inches. The brooch weighs 28.7 grams. It has one small dark spot where the enamel is missing. There is also an age patina on the brooch that I have not cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
