10 mm vintage Czech blue and pink bicone beads

These Czech crystal bicones are an interesting bead. The center is flat, like a rondelle. The ends taper, but do not come to a point. The bead is 8 mm at the widest point. The blue color is concentrated in the center of the bead. The faceting is nice. These beads could be a companion to our 10 mm blue and pink cracked glass beads and 8 mm blue and pink crystal beads. Each strand is 10 inches long and contains 25 beads.
