Gemstone Treatments

v Radiation and heat are often utilized to enhance or change colors.

v A gem’s color is deepened by the use of diffusion. The method only intensifies the outer layers of the gemstone.

v Waxes and oils enhance the color of the gemstone by filling up fine cracks on the surface making them disappear temporarily.

v Gems are coated with a colored or clear epoxy resin or other substances by a method known as fracture filling. This treatment fills out cracks and the appearance of the gemstone is improved.

v Clarity is improved and inclusions removed by laser drilling.

v If the word “enhanced” is used in any form in either advertisements or disclosures, it means that the gemstone has, in some way, been treated.
