Vintage Hobe Clip Earrings Green Blue Beads Rhinestones Round Shape

These clip on earrings by Hobe belonged to my mother. The over all color is green. The main stone is a green bead. I have no idea what it is made out of. It is surrounded by 6 other beads of a lighter color. Hard to say exactly what color they are as they are held in place with a gold like netting. Separating the outer beads are 3 rings of lighter blue beads and 3 rings of what appear to be rhinestones. I am no jewelry expert, and all I can say is that they are in nice vintage condition and quite unique, as I have not found anything exactly like them on the internet.
