How can I tell if an emerald is lab created or lab grown?

Generally, most mined emeralds contain inclusions – internal characteristics formed during growth. It is rare to find eye clean emeralds mined from the earth, and when you do, they are quite valuable and demand extraordinarily high prices! 

Chatham lab grown emeralds have no visible inclusions but are priced far less than a similar quality mined emerald. This is one of the advantages of Chatham lab grown emeralds.
