Pair Of Estate Earrings Clip-on Dangles Blue Stone Setting Unsigned

These earrings are from a local estate so I do not know the history behind them. I am certain they are vintage. I am no jewelry expert, but it appears that perhaps someone added the dangled stones to the original set. It also appears that the clip on one of them has been reglued. I did not attempt to clean these. Please review each photograph provided as our pictures are the best description we have on these.
