Vintage art glass parure jewelry set

I found this set at an estate sale.. No clue where its made,what to call it,so that makes it difficult to research
i have searched many different terms, and google images with no luck~Even searching by each single bead
Necklace,earrings and bracelet
Interchangeable , bracelet can attach to necklace to make it a little longer
The clasps and earrings look like carnival glass?
Has anyone seen something like this, or any clues? Thanks
