Clean using warm water, mild detergent, and soft brush. Never use ultrasonic or steam cleaners on your natural gemstones.
Keep your tourmaline separately from other harder gemstones such as diamonds, sapphires, ruby, topaz, as they might make scratches on the tourmaline.
- Long Term Storage (for Opal) -
Most opals have 6-10% water content and will form cracks if they "dry out". Place your opal in a sealed plastic bag wrapped in cotton wool with a few drops of water just to be safe.
