English costume jewelry ID assistance?
Can y'all recommend a good resource for identifying vintage English costume jewelry? My mom just mailed me some earrings and I'm curious about age. They appear to have a full set of marks (enough for me to figure out where they're from and what they're made of) and all I can figure out from the web is that I should be able to figure out everything from the marks.
Soooooooo...I think I need a book or something. Any recommendations? Thanks!
Or, forget the marks--when did earrings go from screwbacks to clippy thingummies?
