You'll find that the wispy black streaks encircling these Czech glass beads will offer a sense of movement and drama to your jewelry designs. Each bead is beautifully translucent with small streaks of black in varying shapes and sizes. Because of their unique look, you need only to string a few of these beads onto your favorite wire to create a memorable design. Glassmaking in the Czech Republic is an age-old cottage industry. These beads are still made in small quantities by hand, so there may be slight color variation from one batch to the next.
