Opals are very delicate. You have to be very careful when wearing them that you don't bang them against hard surfaces or they can chip or break. They also need to be hydrated and will dry out and get dull if not worn often. Never clean them with regular jewelry cleaning solutions use only watered down toothpaste and a soft toothbrush.
