Your opal should be cleaned on a regular basis. Use a mild detergent in warm water with a soft cloth. Avoid the use of bleach and chemicals, and never try to clean an opal in an ultrasonic cleaner, since the vibrations can cause cracking. If you live in a very dry climate or store your opal for long periods, you can keep it sealed in a plastic bag with a moisture source such as a damp piece of cotton. This will prevent dehydration.
