This is really cool and unique. This Hattie Carnegie (1880 - 1956) pendant is an Austrian coin replica that has been punched out in silhouette with the words Archid Avst Dux Burg Co Tyr 1780. It was designed as a tribute to her Austrian heritage. The pendant is surrounded by a ring of clear rhinestones which is what makes this one rare. Marked on the back, this piece measures 1 1/2" across. One minute section of the rhinestone ring has come loose and needs re-soldered.
