This looks to be from the Victorian era, but there are no marks. It's quite large, for a locket, measuring 2 inches tall, and 1&1/4 inch wide, when closed.. Made of brass, it has a highly ornate, pressed floral pattern on the front. There is some wear to the brass finish, primarily on the back. The clasp and hinge work well. I am guessing that this was a purse, or pocket locket, as there is no pin on the back, and there is no loop for it to be worn on a chain.
NOTE THAT THE PHOTOS HAVE BEEN ENLARGED TO SHOW DETAIL! I currently have several pieces of vintage, and antique jewelry, including other lockets, in my shop, and am happy to combine shipping.To see them all, type the word, "jewelry", or, "locket", in the California Girls search box at the top of this page
