Emerald is the gem of spring, and therefore, the perfect choice as the birthstone for the month of May. It is also the gem of the 20th and 35th wedding anniversaries.
Emerald is the green variety of beryl, but not all green beryl is called emerald. The gem needs to be moderately to strongly saturated in color to be called an emerald. If this criterion is not met, the gem is simply known as green beryl. The most desirable emerald colors are a bluish green to pure green, with vivid color saturation.
Colombia has been the source of the finest emeralds for more than 500 years, and Colombian emeralds are the standard by which all emeralds are judged. A fine emerald with an origin report stating “Colombian”, will command a much higher price in the market. Brazil and Zambia are two other important sources for emeralds. We also have emerald mines right here in the North Carolina mountains, although gem quality rough is harder to find.
Most people think emeralds are soft, while this is not technically true, some emeralds can have durability issues. Emerald is a 7.5 to 8 on the Mohs scale of hardness, for comparison topaz is 7 and quartz is 8. I do not recommend anything below a 7 for everyday wear. Almost all emeralds have inclusions due to the nature of their growth. An emerald’s durability for everyday wear in a ring can come into question based upon the type, quantity, and location of an emerald’s inclusions. All emeralds in Facet Foundry’s collection have been carefully vetted to minimize risk
There are a number of treatments that can be performed on emeralds to alter color, apparent clarity, or improve the durability of the gem. The most common and accepted treatment is oiling, which lessens the visibility of inclusion and may in turn brighten the overall appearance of the gem. Emeralds should only be cleaned with a mild detergent. Ultrasonics and steam cleaners can remove oil treatments or lead to thermal shock.
