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.

Enhancements: Unpolished gemstones are typically very rough. Looking at gemstones straight from the mine, they might be mistaken for pebbles or gravel.

Nearly all gemstones available on the open market have been "enhanced" (i.e. something has been done to make them look better). Gemstones that have not been enhanced are very rare and command extravagant prices.

There are many methods of enhancing gemstones. Some of the most common enhancement treatments are described below. For more information on gemstone enhancements, visit the American Gem Trade Association website

The use of heat to enhance the color of some gemstones is a common practice around the globe and has been going on for centuries. It is part of the standard polishing and finishing process for many gemstone varieties, including aquamarine, citrine, amethyst, sapphire, ruby and tanzanite, and is accepted by the jewelry industry and the American Gem Trade Association.

The enhanced color of heat-treated gemstones is permanent and does not require special care. Aquamarine, citrine, amethyst, sapphire, ruby and tanzanite gemstones offered by Blue Nile have been heat treated.

Colorless oil, wax and resin are used to improve the clarity of some gemstones. The colorless oil, wax or resin is infused into surface-reaching fissures (called inclusions) to improve the stone's appearance. This process began centuries ago by gemstone merchants who found that immersing emeralds in clear oil or waxes made them look clearer to the unaided eye. Today, almost all emeralds are treated in this way. Gemstones with colorless oil, wax or resin enhancement, including emeralds, can be harmed if handled roughly. Recommended special care for such gemstones is avoidance of sudden temperature changes, steaming, chemicals and ultrasonic exposure.

Emeralds offered by Sndgems.com may have been treated with colorless oil, wax or resin.
