Bat Ami, an Israeli designer.

The first one is Frederic Jean Duclos, I believe the second is too. He does electroform work.

Clark & Coombs, could be Smoky Quartz or just glass.

Jezlaine, a manfacturer who does lots in this scroll style.

Items marked Silver are usually from China and are often less than 925/sterling.

It's brass, it was used a lot in Mex jewelry, there is even a store in Taxco, Laton (means brass in Spanish) that specilizes in it.

It's an electroform piece from Israel. I don't remember who the maker is but I've seen the mark many times. There was usually a sticker on the piece with the info but they were often removed at the first wear.

Looks like TS-108 so it was made in Taxco after 1979 by an unknown artisan. The grapes were a popular tourist design.

Most things I've seen marked just silver are from China, this looks like it may have had some enamel in it. They are often less than 925/sterling.

They aren't Mexican, they look to possibly be Hopi.

I"ve seen similar pieces listed as Middle Eastern which makes it hard to date since many of their newer pieces are made just like the older ones.

The mark is Pineda's in a crown, it was used by a brother of Antonio Pineda. The upper left mark is likely TP-17 so they date 1979 to now.
