Back to: The Magic of Birthstones MB1
Emerald has been synonymous with the color green since ancient times. A fine emerald is a truly breathtaking sight, and this member of the beryl family deserves its placement among the traditional “Big Four” gems, along with diamond, ruby, and sapphire.
Symbolism
Legand has it that wearing emeralds will imbue the wearer with heightened intelligence and allow them to think objectively. Others use the stone to promote healing. It has even been claimed that emeralds allow the wearer to predict the future.
Color
The best emeralds express an even, deep green. Some may have blue undertones. Emeralds are known to commonly include eye-visible inclusions. Generally speaking, the fewer the inclusions, the higher the value of the stone.
WHERE ARE EMERALDS FOUND?
Colombia has been the source of the finest emeralds for more than 500 years, and Colombian emeralds are the standard by which all others are measured. Three mining sites in Colombia are particularly noteworthy: Muzo, Chivor and Coscuez. Each locality produces a range of colors but, generally speaking, darker tones of pure green emeralds come from Muzo. Emeralds that are lighter in tone and slightly bluish green are associated with Chivor. Slightly yellowish green emeralds are unearthed in Coscuez.
The May birthstone is also found in the state of Minas Gerais, Brazil. One of the most productive sites for the green birthstone is the sophisticated Belmont mine. Capoeirana is another important locality, a rugged region worked largely by independent miners and small-scale operations.
he May birthstone can also be found in Africa. Zambia is a major source, and mines in the Ndola Rural Restricted Area are known for producing emeralds that are bluish green and darker in tone. Pakistan and Afghanistan are important producers as well.
EMERALD BIRTHSTONE CARE & CLEANING
Emerald is a 7.5 to 8 on the Mohs scale of hardness, so it is more susceptible to scratching than a diamond, which ranks 10 on the scale. The May birthstone is often treated to improve its color or clarity. Common treatment methods include:
1. Dyeing: Paler emeralds with multiple fractures may be dyed green to enhance their color.
2. Fracture Filling: Oils, waxes, and artificial resins are often used to fill surface-reaching fractures in emeralds. The goal is to reduce the visibility of the fractures and improve the apparent clarity. The volume of filler material present can range from minor to significant; the different substances have varying degrees of stability.
The emerald birthstone requires some special care: Avoid exposure to heat, changes in air pressure (such as in an airline cabin) and harsh chemicals. Never put an emerald in an ultrasonic cleaner, as the vibrations and heat can cause the filler to sweat out of fractures. Filled emeralds can also be damaged by exposure to hot water used for washing dishes. The safest way to clean emeralds is to gently scrub them with a soft brush and warm, soapy water.
