While Zultanite® is well-suited to everyday wear, avoid doing anything that risks impact, exposure to chemicals, heat or extreme temperature changes. Always store Zultanite® carefully to avoid scuffs and scratches. Clean with gentle soap and lukewarm water, scrubbing behind the gem with a very soft toothbrush as necessary. After cleaning, rinse with lukewarm water and pat dry with a soft towel or chamois cloth. Never steam or ultrasonic clean your Zultanite®.
