Is it likely this is unmarked Georg Jensen or just a copy?

Hello,

I purchased this brooch and when I looked around online I found what seems to be this exact brooch by Georg Jensen.

Of course the issue is it is only marked "sterling" and it seems the brooch by him I found was always marked with his mark.

Can anyone tell me if he ever left his pieces without a makers mark? At this point I am working under the assumption because of the lack of marks it is a copy.

Thank you all!

Hi,
Dove brooch was designed by Kristian Mohl-Hansen in 1910; meaning one can find various marks for 123 design number (older GJ in a rectangle, or later dotted oval) but always fully marked. It was widely reproduced as bird brooch.
