Below the surface of these Venetian rounds is a combination of amethyst-colored glass, gold and silver foil, and copper aventurina. The unique shapes and layering of these materials create a dynamic bead, rich with dimension. Due to the handmade nature of these beads, there might be rough edges around the bead holes, created where the glass connects to the mandrel. Use a Bead Reamer to remove these sharp edges and smooth the inside of the bead.
