What is the item?

What appears to be a mens ring. Someone mentioned to me over the years that they thought it was Native American.


Can you please provide all background information?
An Aunt of mine from Maryland gave this to me when I was very young. I loved putting it on, she eventually gave it to me. It's been in a jewelry box ever since.


What are the markings?
The top of the ring has 2 feathers along side 2 pieces of turquoise that run down each side. There is one center diamond with 2 circular swirl designs. There is 12-K GF (under that) GW on the inside of the band.


Where are the markings?
The markings 12-F GF GW are on the inside of the top of the band.
