Opals should be protected from chemicals, high heat, and harsh wear. Because opals contain 5 to 10 percent water, some opal has been known to dry out and craze (small hairline cracks) after a short while or even after a lifetime of use in a piece of jewelry. Ideally they should not be stored in dry, air-tight containers like safe-deposit boxes. Opal jewelry should be cleaned with mild soapy water and a soft brush or cloth.
