Never use an ultrasonic, never use chemicals and avoid heat. Don't put your opal ring on the windowsill when washing your hands or the dishes as strong sunlight can dry out the water in opals, which could cause hazing or color change. Also, try to avoid wearing opals in the shower or when in the water because this will also wear down the opals actual size and color.
