Non-Fluorescent Diamonds

Diamonds that emit a colourful glow under UV light are referred to as fluorescent diamonds, and those that don’t are called non-fluorescent diamonds. While fluorescence (especially blue) can make a diamond with a low colour grade appear more colourless, it is generally not desired in stones with a higher colour grade because it can make them appear hazy. Shop brilliant diamonds by selecting non-fluorescent diamonds in an ideal cut.

FAQs about Non-Fluorescent Diamonds

Diamonds that provide a colourful glow under UV light are considered fluorescent. Fluorescence isn’t typically considered a performance characteristic of a diamond, and strong fluorescence isn’t a desired quality in diamonds.

Yes. A fluorescent diamond is roughly 15% less expensive than a non-fluorescent diamond of comparable quality and carat weight.

Fluorescence is only visible under UV light, but it can make a diamond appear hazier under bright natural light than a non-fluorescent stone would be.

According to the GIA, while fluorescence is not graded, it is an important characteristic of diamonds. The level of fluorescence in a diamond can be regarded as none, faint, medium, strong, or very strong. If it is medium or higher, the GIA grading report for the diamond will note the colour of fluorescence.

Non-Fluorescent Round Cut Diamond Review


One of my friends used the Blue Nile website to look for an engagement ring about 15 years ago and that's how I heard about the company. My boyfriend and I recently started looking for a diamond ring, and after we looked at a couple diamonds from jewellers he knew, we decided to look on the Blue Nile website. We were very impressed with the selection, and after 3 days of many phone calls to the customer service representatives at Blue Nile to ask for information and opinions on the diamonds that we were interested in, we finally decided on a 2.5 Carat, D colour, S1 2 diamond. The image of the diamond was perfect, 3D and spinning so we could see it from all angles. We had the diamond set in a Blue Nile setting, and it was delivered to my home about 2 weeks later. The ring is beautiful, the service is exceptional. We highly recommend this website and would definitely buy from Blue Nile again.
