The aquamarine color in the center of these beautiful Venetian cubes provides a gorgeous foundation that is contrasted gorgeously by gold and silver foil. Specks of copper aventurina provide another rich dimension of brilliant color. 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.
