Opal, with a hardness of 6.5 on Moh's scale, is a delicate and captivating stone. Composed mainly of hydrated silica and containing 6-10% water, opals shimmer with a unique iridescence. However, these precious gems must be cared for carefully to maintain their beauty. In very dry conditions, opals may crack, known as "crazing."
To clean solid opals, gently use a soft sponge or cloth with lukewarm water and mild detergent. Avoid using bleach and harsh chemicals, as they can damage the stone. Ultrasonic cleaners should also be avoided for cleaning opals.
If your opal has lost its shine or become scratched over time, it can be re-polished to restore its lustre and smooth surface.
Due to their softness, opals should not be worn with other jewellery that could potentially scratch or damage them. When storing your opals, place them in a padded cloth bag and consider leaving a small glass of water in the enclosed space to help maintain their moisture. Alternatively, you can place your opal on cotton wool soaked with a few drops of water before storing them away. This will ensure that your opal remains hydrated and pristine for years to come.
