Very pretty round blanks for a 14mm cabochon. These feel lovely and strong. They have a pretty beaded border, and around it, a large scallop that will allow you to connect these with a jump ring to a chain or to more trays. The overall diameter is 25mm and the internal diameter for the cabochon is 14mm. They measure approx. 2.5mm thick and are made of zinc alloy that is free of lead and nickel. Available in antique bronze finish.
