Help with a sterling ring makers mark

[Penguin]

Hello,

I was hoping someone could help me identify the maker of this ring.

Also I wanted to find out what kind of stone it is and if its "normal" to facet the back of the stone as is done here.

Any thoughts or information would be appreciated!

Cheers,
K

Hi,

Looks like Native American. I'll move the topic to that section.
