Trying to Read a Jewelry Stamp

[AgIA]

Found this puzzle ring today and I'm pretty new to the jewelry finds so I'm trying to figure out what it is. I think it might be junk although it has some sort of marking but I can't tell what it is. The picture of the ring is a little misleading as it is silver colored not the golden shade produced by the lighting. I suppose the mark might also be upside down but this looked most correct to me. Any help is appreciated!
