Strass (rhinestone) is a cut lead glass, also called crystal glass, with increased light refraction properties. It is most often used for manufacturing gemstone imitations. A small hole is pressed into beads, pendants or components, where the chatons are then fastened. You can use chaton jewellery components for threading, sewing or gluing, while using rhinestone beads you can easily create impressive shamballa bracelets.
