Featured Hallmark identification on 18k pendant

Hello

I wonder if anyone can identify hallmarks on the pendant I acquired recently.
I know there is a Gubelin hallmark but there are two others as well.
Trying to figure out if it was made by Gubelin or just retailed by it.

Thanks much.

 

where's the 18 k mark?

 

Here it is

 

The one on the right is the Gübelin logo/mark


I think we'll need to see a pic of the other mark from a different angle.
