Diamond Fluorescence

Diamond fluorescence is a fascinating phenomenon that occurs when a diamond emits a colored glow when exposed to ultraviolet light. This unique characteristic is a result of the diamond's atomic structure and can have a significant impact on the appearance and value of the stone.

What causes diamond fluorescence?

Diamond fluorescence is caused by the presence of trace elements, such as nitrogen, within the diamond crystal. When these elements interact with ultraviolet light, they absorb the energy and re-emit it as visible light, creating a colorful glow. The intensity of the fluorescence can vary from faint to strong, depending on the concentration of these trace elements.

Does diamond fluorescence affect the value of a diamond?

The impact of diamond fluorescence on the value of a diamond is a topic of debate among experts in the industry. Some believe that a slight to medium fluorescence can actually enhance the appearance of a diamond by making it appear whiter and brighter. However, diamonds with strong fluorescence may appear hazy or oily, which can lower their value.

How common is diamond fluorescence?

Approximately one-third of all diamonds exhibit some degree of fluorescence when exposed to ultraviolet light. The most common fluorescence colors are blue and yellow, but diamonds can also fluoresce in other colors such as green, orange, or red. The presence of fluorescence is typically noted on a diamond's grading report.

Can diamond fluorescence be detected?

Diamond fluorescence can be easily detected using a UV light source in a controlled environment. Gemologists use specialized tools to assess the fluorescence of a diamond and determine its intensity and color. This information is important for accurately grading and pricing the diamond.

Overall, diamond fluorescence is a fascinating characteristic that adds to the complexity and beauty of these precious gemstones. Whether it enhances or detracts from the value of a diamond is subjective and depends on personal preference. Understanding the science behind diamond fluorescence can help you make informed decisions when purchasing a diamond.
