Crystals beads are made from glass which is cut to form multiple facets and designs. The dual tone beads have a mixture of two complimentary colours and generally have a metallic look. Each bead features a crystal clear hole with smooth edges to help protect the stringing material. Highest quality glass is used in production which is pressed in a mold then precisely faceted by machine and polished in a direct fire. The advantage of a fire polishing technique is a softer gentler appearance to these scratch resistant beads.
