Have you ever noticed the term "Fluorescence" in a GIA Diamond Assessment Report? Did you know that some diamonds show effects under ultraviolet light? For most people who buy diamonds, fluorescence will not be a problem, but some may be mistaken for the term. Below you will find frequently asked questions and useful answers from GIA researchers who have studied deep fluorescence. What is diamond fluorescence? The fluorescence of diamond, in its simplest form, is the effect that ultraviolet (UV) light has on a diamond. When you stand under the blue or ultraviolet light, you can sometimes see that your whites are getting brighter or your teeth seem to shine. This is the same effect that diamond has under UV rays. Fluorescence is the visible …show more content…
While a professional will have the definitive opinion of whether a diamond is genuine or not, there are ways to detect a fake. Fake diamonds differ from real diamonds in many ways. Ultraviolet light, also known as black light, will reflect the differences in most diamonds, making it a useful tool for the detection of rhinestones. Buying a diamond is a great investment, which can even be transferred to your family. He will want to be sure that he receives the real. Hold the diamond in question under a long ultraviolet light (also called black light). If the diamond reflects a blue fluorescence, it is very likely that it is authentic. Keep in mind that while most diamonds on the market have a blue glow under ultraviolet light, high-quality diamonds will not. The ultraviolet light method must be performed with other tests to detect a fake diamond. Be aware that cubic zirconia will shine mustard yellow under ultraviolet light. The glass will have no brightness at all. Familiar with other methods of detecting faux diamonds, such as reflection colors in stone, weight, quality parameters and wear of the stone
