What to look for when buying an Emerald.

• Cut: Due to their crystalline structure Emeralds are most commonly cut in Square and Octagon shapes. Round and Ovals cuts are also widely available. Fancy cut are very uncommon in Emeralds.  
• Color: Emeralds occur in a variety of green colors, from a light luminescent blue/green to deep rich emerald green. Chromium and Vanadium are what give Emeralds their extraordinary color.
  Valuable
• Clarity: Emeralds should have inclusions. Specks of carbon, fractures, cloudiness and silk inclusions are all common and should be seen in a natural minded from the earth Emerald.  Silk inclusion can not be created in a lab and is an excellent sign the Emerald you are looking at is the real thing.  An Emerald that is large, very green and has no flaws is highly suspicious.
• Cost: Small light Emeralds can be purchases for just a few dollars.  Large Emerald can cost many thousands of dollars!
• Care: Emeralds should be cleaned with a soft, dry cloth. You should never clean an emerald with an ultrasonic cleaner. Ultrasonic cleaners can easily damage you gem.  Emeralds are heat sensitive, avoid sudden temperature changes as emeralds can lose their color when strongly heated. Do not wash Emeralds in hot soapy water, this can dry them out.
• Treatment: Oiling,  the oils seep into the breaks and fissures in the gemstone to  'soften' the appearance of  flaws.  This is done to nearly all Emerals.
