Add these crackle-finished Czech glass fire-polished beads to your designs, and you'll be adding a classic element with a modern flair. Czech glass fire-polished beads are hand-crafted in the traditional manner, giving them a classic feel. The crackle finish on these beads gives them an almost bi-tonal appearance. The look is truly modern and would work well as a contrast to pearls and other traditional jewelry components. These beads are made in small quantities by hand, so there may be slight color variation from one batch to the next.
