Don’t Let Fluorescence Scare You

“How does fluorescence effect my diamond?”




Don’t Let Fluorescence Scare You

(PRESS RELEASE) The answers are not always easily explained as retailers view fluorescence quite differently. Some may feel that their geographic location in snowier parts of the country is not good for diamonds that may have fluorescence while others love fluorescence and its effects, and other retailers may be indifferent. The fact of the matter is that with the increase in demand for diamonds and diamond jewelry and their limited supply, resourcing the “perfect” diamond may be limited.

GN Diamond has an inventory of over 9,000 natural diamonds and over 7,000 lab created diamonds in all shapes, sizes, colors, clarities, fluorescence, non-fluorescence, and price points. One of the features that GN Diamond offers on all of its natural certified diamonds is 3rd Party Light Performance. When this light performance score indicates an excellent or very good and has medium to strong fluorescence it helps retailers sell the diamond and reduces/eliminates consumer concern over the brightness of the diamond.

We look to GIA as being one of the expert resources to help conquer end consumers fear of fluorescence. Here is what they say:

Can an average person tell the difference between diamonds that do and don’t fluoresce?
GIA has studied the effect of blue fluorescence on diamond appearance. The Institute screened a large number of diamonds, assembling four sets of six diamonds, with each group representing a different color grade (E, G, I, and K). The diamonds in each set were as similar as possible in all respects except the intensity of blue fluorescence. Diamond graders, trained professionals, and average observers viewed the diamonds in controlled conditions to make a judgment about their appearance.

Here is what GIA found: “For the average observer, meant to represent the jewelry buying public, no systematic effects of blue fluorescence on the face-up appearance of the groups of diamonds were detected. Even experienced observers did not consistently agree on the effects of fluorescence from one stone to the next.”

Simply put, blue fluorescence had a negligible effect on the face-up appearance of diamonds in the colorless or near-colorless grade ranges (grades D through J) except for a slight improvement in the rare instances of very strong fluorescence intensity.


GIA answers, “Is diamond fluorescence good or bad?”
Fluorescence is neither good nor bad. A diamond’s beauty is in the eye of the beholder. You may perceive fluorescence, or you may not. You may like it, or you may not.

GN Diamond’s extensive inventory of natural, loose diamonds may be viewed here. We are open 7 days a week with any questions, simply email us at or call us at 800-724-8810. We also now carry a full inventory of lab grown diamonds all made in the USA with all shapes and sizes.



When the Kids Have Their Own Careers, Wilkerson Can Help You to Retire

Alex and Gladys Rysman are the third generation to run Romm Jewelers in Brockton, Mass. And after many decades of service to the industry and their community, it was time to close the store and take advantage of some downtime. With three grown children who each had their own careers outside of the industry, they decided to call Wilkerson. Then, the Rysmans did what every jeweler should do: They called other retailers and asked about their own Wilkerson experience. “They all told us what a great experience it was and that’s what made us go with Wilkerson.” says Gladys Rysman. The results? Alex Rysman says he was impressed. “We exceeded whatever I expected to do by a large margin.”
