Hi, welcome to Tnet. I can see the 925, so for sure the ring is silver. Not sure,who the maker is but there are a zillion silver marks, so you may never find that out. Nice ring though.
Hey IDCAM - Your find is a basic silver ring, FNA is most likely the designers initials or company. I have found several rings, bracelets, necklaces with the same marking - So, sorry, it's nothing out of the ordinary - but hey, still a nice find!!!! Keep on truckin brotha, the GOLD is out there just waiting to be found!!!!!!!!!!!
