This Red Murano Glass Sterling Silver Bead has a sterling silver core. The bead itself is made of a mix of clear and coloured glass to build up the pattern. This process dates back hundreds of years and was widely practiced in Murano, Italy in the 14th century. The glass bead has become very popular on charm bracelets. It will fit our standard size charm bracelets and other charm bracelets like Pandora and Trollbeads. You can create a traditional beaded bracelet with different coloured sterling silver beads. This bead will be a beautiful addition to your charm bracelet. Each charm bead is unique, our beads are hand-made by craftsmen, and there will be slight variations in color and positioning of designs.
