Granat perl silver necklace Whi Is The Maker?

Unknown maker; there is no complete list of maker’s marks in Germany. Unlike in many other countries you do not have to (and never had to) register.
Judging by its appearance it was most likely made in one of the hundreds of jewelry manufacturing companies in Pforzheim or Schwäbisch Gmünd, but it could also be made anywhere else in Germany.

Die Muster auf den Bändern wirken für mich auch nicht wirklich alt.
