ABOUT GEMS: TREATMENTS AND ENHANCEMENTS
Today, most gemstones are enhanced or treated. Although many of the treatments are stable, some are not.

Diamonds
A DiamondCommon diamond treatments today are clarity enhancement and laser drilling. Clarity enhancement is the process in which imperfections are filled with a glass-like substance to improve the appearance of the diamond. Extreme heat, such as that from a jeweler’s torch, or specifically formulated chemicals can remove the filler.

In laser drilling a laser is used to reach dark inclusions within the diamond. Often a bleaching agent is added to make the inclusion less visible. Laser drilling is stable.
