Opal contains 3–21% water, so avoid extreme heat, ultrasonic cleaners, and prolonged direct sunlight. Clean with a soft damp cloth and store away from dry environments.
Opal's play-of-color comes from light diffracting through stacked silica spheres within the stone. The size and arrangement of these spheres determine which colors appear.
Opal rates 5.5–6.5 on the Mohs scale, softer than quartz. Pendants work well for regular wear because they hang against fabric rather than contacting hard surfaces like rings do.
