There are classics in the bead world. Even amongst those classics, there are real classics. These are just one of those very classics. These are described in the trade as Czech glass "6mm crystal AB druks". The "AB" designation is short for "aurora borealis", which is a metallic finish applied to the beads which plays with the light in such a way to show off a shimmering rainbow of colors. The term "druk" is fancy-talk for "round". No bead collection is complete without these sparkling beauties. They lend themselves to any bead project wih their pearly, shimmering rainbow finish. They are $1.50 for twenty five beads.
