Emerald is the most famous member of the beryl family. Legends endowed the wearer with the ability to foresee the future when emerald was placed under the tongue, as well as to reveal truth and be protected against evil spells. Emerald was once also believed to cure diseases like cholera and malaria. Wearing an emerald was believed to reveal the truth or falseness of a lover’s oath as well as make one an eloquent speaker. Use a soft micro-fiber cloth to remove the oil and dirt accumulated on the emerald jewelry. Do not use an ultrasonic cleaner on emerald jewelry. Ultrasonic devices and commercial jewelry cleaners will remove the oils that the emeralds have been treated with and will cause damage to the gemstones. Always put your jewelry on after you’ve applied make-up, hairspray or perfume, or the chemicals may damage the emeralds.
