Here is a Victorian pendant or watch FOB. I believe that it is made of dark amber glass. It looks black but when held up to the light it has an amber color. The reverse side is plain and smooth. There are tiny etchings on the gold filled setting. With the setting the piece measures 7/8" X 1 1/8". Very nice condition.
