Frosted blue nautilus beads

These vintage glass beads were made in Czechoslovakia during the 1990s in molds. The bead is a light blue and frosted so that it is translucent. There is an incised pattern that looks like a swirl or gives the bead the impression of being a stylized nautilus shell. The bead is 13 mm from hole to hole and 12 mm across. The edges are rounded and smooth with no mold marks. Price is for 10 beads.
