Featured Brass jewelry lot, info on age and origin?

Hello all, happy Friday! I picked up this jewelry lot from auction recently described as "Victorian brass jewelry lot". I'm finding that descriptions from auction houses are very often inaccurate. I'm think many of them are from the 1920s-30s, the festoon necklace maybe even mid century? Since there a quite a few pieces, if you could let me know if there are any older than the 1930s (if even that old ), that would be appreciated. One of the brooches appears to be a button converted into a brooch, it says "Depose Paris". Maybe some Czech glass in there? Any info on age or origin of any would be appreciated, thank you!

 

The book chain is really unusual, which just means that I haven't seen one like it before.

 

Black brooch says depose Paris. Started as a button, someone glued that back on.

The other brooch looks mid to late nineteenth and is a very nice thing.

 

Yes thanks! I mentioned that I thought it was a button . The dangle brooch is mid to late 19th century? Was the pin replaced fo you think? It doesn't have an old tube hinge.

 

Duh, I missed that!

The hinge on the dangle one predates tube hinges by the look of it.

 

Ooh, interesting- thank you! I assumed it was a 1930s revival type dangle brooch. That's great
