Gorgeous flashy 6mm black and 4mm white Kyocera opals in an asymmetric silver wire wrapped cuff. Kyocera opals are lab grown but just as beautiful as a natural opal. Opals are a birthstone for October, and are thought to lend a sense of balance to the wearer. As with all opals, care must be taken to keep them away from detergents and abrasive cleansers to avoid damaging them. Fits up to a 7 inch wrist.
