Enhancement is often used as another word for treatment. Enhancement also refers to the faceting and polishing of a gem. For centuries, ruby, emerald and sapphire have been in heat treated to improve their color. Heat treating is widely accepted because it is a continuation of a natural process and it causes a permanent improvement of the entire gemstone. From the standpoint of value, it does not matter whether commercially-quality stones have been treated or not as long as the color is permanent. The overall quality of the treated stone will determine the price. However, a premium may be charged for high-quality untreated stones that comes with a lab report stating there is no evidence of heat treatment.
