DIAMOND FLUORESCENCE

What is Diamond Fluorescence?

Diamond Fluorescence  is a great tool to lower your diamonds price.    The technical explanation is the effect that Ultraviolet rays(UV) have on the diamond. In a simple and fun explanation, your diamond can turn into a glow stick(kidding but not really). A Diamond with strong Fluorescence, under a UV light, can have a strong blue color. In the real world, unless you are in a club under black light, It wont be glowing blue. In the day time or regular lighting you wont have a glowing diamond. With medium to very strong fluorescence grades, A trained eye may see a little hint of blue. However, if your diamond is lower in color it cancels out the yellow.

Its very common to find fluorescence in diamonds. Approximately 25% – 35%  show a degree of fluorescence. However, only 10% of diamonds with grades of medium, strong or very strong fluorescence  may affect appearance.

Here is a sample photo from GIA . It shows a necklace made of diamonds that are strong in fluorescence. One half is viewed with normal lighting. The other half with fluorescent lighting.

How does fluorescence effect the diamond

GIA studies show that for the overwhelming majority of diamonds, the strength of fluorescence has no noticeable effect. In conclusion to a GIA Fluorescence Study,  the average person could not tell the difference between a diamond with fluorescence and a diamond without. So whats the big fuss about!?  There is a very low percent of diamonds that have a hazy look to them due to strong Fluorescence.  To be exact, less than 0.2% of fluorescent diamonds submitted to GIA exhibit this effect.

Because of the possible(extremely rare) haze effect. The industry has labeled fluorescence a negative feature that gets a discounted price.  You can expect a 2% to 16% savings.

I SEE DIAMOND FLUORESCENCE IN A POSITIVE LIGHT! If you recall, yellow is the most common color found in diamonds.  And BLUE is a complimentary color.  Diamond Fluorescence can give your yellow color diamond a white appearance.  Hence giving you incredible value if purchasing a K-J color Stone.

IN CONCLUSION

I see nothing wrong with fluorescence. If you are buying a lower color diamond, I recommend a medium to strong fluorescence. If you want to splurge with a high color, understand that the blue may stand out. You don’t want to buy a D-F color diamond with strong fluorescence. Anything under H is a go!  The lower the color grade the stronger the florescence can be to help cancel out the yellow.  I have had clients think it looks beautiful and prefer it.  It goes down to preference. Remember read my diamond color article to learn each  diamond shape has an ideal color scale.

 

Recommended Places To Buy

For me to recommend any business, they must meet certain criteria. They must prove valuable to my clients in regards to How to buy a diamond savings and selection | EXPECT 20%-40% LOWER PRICES THAN TRADITIONAL JEWELERS |, time doing business(legitimacy), reputation, and return policy.

James Allen Logo

James Allen  is my favorite vendor.  They revolutionized the ability to get the clearest image of a Diamond with a 360 degree HD image/video and a zoom in up to 40x on all their Diamonds. This without question leaves no doubt on what you are buying.  I argue the ability to see your diamond more clearly than in a physical retail store is a massive plus for you.  They have incredible prices that I will easily  beat retail store pricing.  They have an a amazing 30 day Free no hassle return policy and have been in business for over ten years with countless positive reviews from real customers. The only Con is they are slightly limited in the search filtering ability. Blue Nile  has a deeper way of filtering certain attributes.  Click on this link or Picture to search their inventory.

Blue Nile was the original online giant that opened in 1999! They probably have the largest selection. In the past they didn’t have images of their inventory but because of James Allen , they were forced to adapt and they now have a large amount of their inventory with images.  There viewing technology is not as good as James Allen  but its still clear and one can evaluate a Diamond with confidence.  Blue Nile  has an incredible 30 day free return policy as well that is insured.  The only Con is they do not have AGS certified goods on their site.  This isn’t an issue for round diamonds but very helpful with fancy shapes like Princess, Cushion, Oval etc… Click on this link or the Blue Nile Logo to see their inventory.
