Then comes Carat, Cut, Color and Clarity.



Fluorescence
Not technically a 4C, but just as important.
“Bonnie, I only want to buy a diamond with no fluorescence”.
Wait a minute, let’s first understand, what is diamond fluorescence?
Fluorescence is the glow you sometimes see in diamonds when exposed to UV rays from sources like the sun, causing them to emit a bluish light. A very common misconception, “If a diamond has fluorescence, it doesn’t sparkle as much”. That’s simply a false statement. Bonnie owns plenty of diamonds with fluorescence in her personal collection. (And they sparkle a lot)
If you read enough online articles, you will often read “avoid fluorescence because it can cause milky or cloudiness in a diamond”. Well, yes it can. But what percentage of it actually does?
0.02% out of all diamonds submitted to GIA with strong fluorescence actually appear hazy or oily. You read that right!
GIA studies show that for the overwhelming majority of diamonds, the strength of fluorescence has no widely noticeable effect on appearance. In the GIA Fluorescence Study, it was found that the average person could NOT make a distinction between a diamond with fluorescence and a diamond without.
And in many instances, observers actually prefer the appearance of diamonds that have medium to strong fluorescence.
Fun Fact: Fluorescence actually helps lower color grade diamonds look much whiter!
Interesting right?
If you have seen as many diamonds as our team have in the past decade, you will understand why rejecting diamonds simply because they have fluorescence is silly and adds more weight onto your wallet!
Trust the By Bonnie Curation process, and you will be happy to know that we have your back on ALL aspects of your diamond. And most importantly, SPARKLE!
