These Venetian round beads are full of color and brilliance. Just below the transparent surface is black glass with pieces of silver and gold foil along with specks of copper aventurina. The layering of these materials provides a dynamic bead full of 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.
