Lovely Vintage (not sure of the age) Sterling Silver and Green/White Striped Agate brooch. the Brooch is marked Silver on the back, and there is another mark on a little box on the back, that I can't quite make out, and 2 signatures on the actual agate that I also cannot make out. the brooch has a lock on the pin back, and the bezel setting is silver. It is 1 3/4 inches wide, and 1 1/4 inches long. It is a lovely piece of Vintage Jewelry.
