Brooch ID marks Silver Diamonds Emeralds

[pinksteel]

Hello, I have a pin that has several marks that I cannot identify. The pin has old cut diamonds and cabochon emeralds set in silver, with gold pin findings and accents. There are marks on the pin stem and on the silver.
Thank you.

Does any anybody recognize any of these marks? Or what they are? On the three silver marks, one looks like a rooster head, could that be right? And one looks like a plant, to me.
I have nothing to go on to even search for these marks.
Thanks again!
