Care for Emeralds:
Do not use an ultrasonic cleaner on emerald jewelry. Rather, scrub with a soft toothbrush and lukewarm water with a mild dish-washing soap. Use the brush to get into those hard-to-reach areas and clean them thoroughly. Rinse and dry the jewelry with a soft clean micro-fiber cloth.
Never wear your emeralds while showering, swimming or sleeping. Always put your jewelry on after you’ve applied make-up, hairspray or perfume, or the chemicals may damage the emeralds. Emerald jewelry can be easily scratched, so be sure to store it separately from other gemstones.
