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. 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. These beads are dyed on the inside with delightful colours with the outer surface staying transparent. These beads can easily be used for embroidery stitching and crafting purposes.
