Diamond Fluorescence

Diamond fluorescence is a natural phenomenon that causes some diamonds to emit a visible glow when exposed to ultraviolet (UV) light. This effect can be seen as a blue, yellow, or greenish glow, and is caused by the presence of certain elements within the diamond's crystal structure, such as nitrogen.

Diamond fluorescence is graded on a scale from "none" to "very strong" and can affect the appearance and value of a diamond. Diamonds with strong or very strong fluorescence may appear hazy or milky in certain lighting conditions, which can lower their value. On the other hand, diamonds with medium or faint fluorescence can appear whiter or brighter, which may increase their value.

It is important to note that not all diamonds fluoresce, and the intensity of the fluorescence can vary even among diamonds that do. The presence and intensity of fluorescence are determined during the diamond grading process and are included in the diamond's grading report.

When purchasing a diamond, it is important to consider the level of fluorescence and how it may affect the stone's appearance and value. A reputable jeweler or gemologist can help you determine the best diamond for your needs and preferences.
