E Pearl Brooch Plus Other costume Pieces

I got some signed costume Jewelry in a box lot years ago which I just "Re-Discovered" while cleaning out some boxes. The one piece I wonder most about is a flower brooch signed E. Pearl. It has enameled Petals and goldtone back. no other markings. Any info you can give would be helpful! Also have some other ocommon Monet pieces. will post a photo of all just in caser I have a fortune hidden in here LOL
In this last Picture, the buckle looking brooch and the butterfly are both marked MONET. The top left is a scarf slide marked 925, but has another indent that looks like it might be a makers mark, but it is totally unreadable. The top right "sweep" pine is marked 4KT gold filled West Germany. Thank you in advance for any help or insight!

 

The flower brooch is likely Erwin Pearl
