rhinestone brooch - German art deco?

[ZoeZoe]

Please help me identify this mark - a shield with what looks like KP inside and a P outside. I believe it is German. The P is the date mark perhaps?

Thank you.

Hello, that is Knoll & Pregizer from Pforzheim, Germany. This mark was used in the 1920ies to at least the 1940ies. The P is not a date letter, it could have been added later by a retailer. Best wishes, Bahner
