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. |
