Material Glass Shape Tyre / Rondelle Crystals beads are made from glass which is cut to form multiple facets and designs. These crystal beads are fire-polished to give extra shine and without any sharp or pointed edges. The faces of the bead reflect a large amount of light which in turn creates a magical sparkling effect. These faceted crystal beads come in beautiful shapes like rectangle round cone rondelle briolette etc. 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.
