This Brooch is an unusual type of silver 835. German made. Narrow with delicate filigree design. Can be used as a set with another of my listings as patterns match. Worn by my Grandmother. Circa 1945. Unofficially appraised by my cousin who is a jeweler/gemologist- no paperwork. Must be able to come to my home to pick up. Cash only please.
