Emerald is a gem quality green "beryl," the same family of stones as blue aquamarine and pink morganite. It is estimated that Colombia produces 70-90% of emeralds on the world market, though in addition, extra-fine grade stones are known to come from Zambia and Brazil. Inclusions are common and expected to be seen in emerald; it is widely accepted practice for gem cutters to conceal inclusions by soaking stones in cedarwood or grapeseed oil. Most stones available on the market have been treated this way.
Though emerald is a hard, scratch resistant 7.5 to 8 on the Mohs hardness scale, we strongly advise to wear emerald rings with care. Stones can be brittle and subject to chipping or breaking on sharp impact. Do not clean emerald jewelry in an ultrasonic cleaning machine or with a steam cleaner. Clean with mild soap, water, and a soft bristled toothbrush. Avoid soaking emerald for long periods of time to preserve any assumed oil treatments in the stone. Should these treatments be compromised, most jewelers can fix them.
