The inside holes of these glass beads have been lined with metal, adding depth to their coloring. These versatile beads can be used with crystals for an elegant evening look or they can be used with pewter components and other glass beads for a more casual everyday look. Glass making in the Czech Republic is an age-old cottage industry. These beads are still made in small quantities by hand. We work with the finest vendors and have the most consistent, beautiful glass available. Due to the way the glass is made, there may be slight color variation from one batch to the next.
