Care and Quality
Clean opal necklaces with a soft damp cloth. Avoid steam cleaning, ultrasonic cleaners, and harsh chemicals. Remove before showering, swimming, or applying perfume. Opal contains natural water and is sensitive to sudden temperature changes and prolonged moisture exposure. Store separately from harder gemstones.
