The listing, Rose Locket Oval Charm For Necklace, Big In Goldtone has ended.
This locket is actually big enough to fit pictures into! It measures about 1 3/4" long not including the bail, and 1 1/2" wide (when closed).
It's a pretty, shiny goldtone metal. No maker's marks of any kind. The design is a rose over a sort of honeycombed background. It snaps shut securely. The bail even has a little detailing on it.
The greenish tinge in the third picture is a trick of the light - the back of the locket is the same pretty bright goldtone as the front.
It's an older locket - probably not vintage yet. Not brand new, but still nice.
