My beautiful antiue glass cameo earrings

This beauties were bought for me a long time ago by my husband for only 40.00 (that was a ton of money to us back then!) at an antique show. They are bezel set oval etched ,carved glass with a tiny cameo carved into the center from the back. They are accented with pearls freshwater, I think. They are not marked anywhere I can see. About 1.5 in. not including the ear hook. I have no idea of their age or country of origin. Im super curious!
