Hi, I was wondering if anyone might be able to help identify any of these marks on silver rings. CA and NF are listed on Illusion Jewels unknown marks pages, but the photos I have are substantially better (thanks to advice I've gotten reading here and around the web). Any help on possible dates of manufacture, style, etc. would also be greatly appreciated. This is the first time I've ever posted pictures, so if I screw it up, forgive me. I'll get it right eventually. Thank you, Meriann
