GIA is now including a fluorescence insert with its diamond grading reports in an effort to educate consumers and build confidence when making a purchase.

The Gemological Institute of America (GIA) is helping consumers see the light by including a four-colour insert on fluorescence in its reports.

Addressing frequently asked questions, the insert accompanies GIA’s diamond grading reports on diamonds with a fluorescence description of medium or stronger. It uses everyday language and includes comparison images of diamonds in natural and ultraviolet (UV) light.

“Some diamonds show fluorescence and some don’t,” said Thomas M. Moses, GIA’s senior vice-president of laboratory and research. “Fluorescence is the emission of visible light by a diamond when it is stimulated by invisible UV rays. It is a common characteristic of diamonds. The diamond simply glows under the UV lights, usually a blue colour, which most often stops when the energy source causing it is removed.”
