Opal: iridescent, glimmering, unlike any other gem. Three cushion-cut opals, framed by twinkling diamonds, shimmer in this 14K white gold ring. As October's birthstone, opal would make an excellent birthday present. Due to the nature of pre-owned jewellery, the ring you choose may have been previously sized. Ring styles from our pre-owned jewellery inventory are sold at their current size and cannot be resized at purchase. As this inventory constantly changes, we are unable to state or guarantee the size of any pre-owned ring.
