Does anyone recognize this hallmark?

Hi,

I'm trying to identify the origin of an estate ring I just picked up. Do you recognize this hallmark?
Does anyone know where I could find a library of common modern jewellery hallmarks? I've found databases for silver marks, but not others.

Thank you so much!

It's a painstaking process but there is a database of trademarks in this link

http://tess2.uspto.gov/

good luck in your search

Thanks montage creations !
I had come across that database earlier, but I'm not sure how to use it properly. I guess I have some reading -up to do
