Fluorescent Diamonds

Fluorescent diamonds emit a colourful glow under UV light. This fluorescence can appear in many hues, but the most common is blue. Fluorescence can be a benefit when you have a diamond with a lower colour grade, because blue fluorescence makes a slightly yellow diamond appear more colourless in natural sunlight.

FAQs about Fluorescent Diamonds

A diamond with fluorescence will emit a soft colour when exposed to ultraviolet light. Although fluorescence isn’t typically considered a performance characteristic of a diamond, a strong fluorescence is not a desired quality in diamonds.

Yes. On average, a fluorescent diamond is 15% less expensive than a non-fluorescent diamond of comparable quality and carat weight.

In most cases, no. If there is a diamond with extremely strong fluorescence, it may seem slightly hazy in bright, natural light conditions.

Although fluorescence is an identifying characteristic of a diamond, the GIA doesn’t consider it a graded characteristic like the 4Cs are. Still, there are different levels of fluorescence. The diamond will either have none, faint, medium, strong, or very strong fluorescence. If it is medium or higher, the colour of fluorescence is noted in the diamond’s GIA grading report.
