It is customary to treat most gemstones to achieve enhanced color and durability. Some of these treatments may not be permanent, and may require special care. AX recommends that you clean your jewelry periodically either with a non-acid-based cleaner or in a solution of mild dish soap and warm water with a soft brush or cloth. Do not use ultrasonic steam cleaners to prevent stones from falling out of their settings. Avoid strong detergents, heat, pressure - colored gemstones may fade in constant light or with heat.
