Emeralds: Emeralds have been celebrated for their vibrant color throughout history; everyone from Cleopatra to Elizabeth Taylor has loved their rich green hues. Though beautiful, emeralds have the reputation as a brittle stone- here are a few tips to keep your emeralds looking great for generations. Caring for Emerald Jewelry - When cleaning your emerald jewelry, be sure to use a jewelry cleaner that does not contain any harsh chemicals that could harm either your gemstone or the setting. - It is best to clean your emerald jewelry only a few times a year. Cleaning emeralds too often will remove the oils used on the gems. - Never use ultrasonic cleaners or steam cleaners to clean emerald jewelry- natural inclusions make them prone to breakage. - Store your emerald jewelry separate from your other jewelry- other gems and metals can easily scratch your emeralds. Everyday Tips: - Despite being close to sapphires and rubies in hardness, emeralds typically have natural inclusions that make them more prone to breakage. - Wear your emeralds with care- they are less durable than diamonds and rubies and wearing them during strenuous physical activity can easily scratch or dent them. - Many emeralds are treated with oils to make small, natural inclusions less prominent. Every 2-5 years these gems need to be re-oiled.
