8 mm lilac round beads

I'm pretty sure these are vintage German, but they could be Czechoslovakian. I am sure they are beautiful and interesting. The bead was made in a mold and has a delicate, almost petal-like pattern pressed into it. There is a darker band of purple running around the equator of the bead. The bead is 8 mm at the center and will accommodate up to a 0.5 mm string. Price is for 10 beads.
