These 6mm peridot opal fire-polished beads are made from faceted translucent light green Czech glass. Occasionally you'll notice a slight glow as the light catches the opalescent properties of the beads in this 50-piece pack. Glass making in the Czech Republic is an age old cottage industry. These beads are still made in small quantities by hand. Due to the way the glass is made, there may be slight color variation from one batch to the next. Be sure to explore other colors and sizes of our Czech fire-polished glass beads.
