Diamond Fluorescence Guide – 4C’s
Diamond shopping trivia doesn’t end at the 4 C’s- clarity, cut, color and carat. There is more to it then you might think. Though these 4 C’s are extremely crucial at making an informed diamond purchase decision however, even the most confident and knowledgeable get confused when they see the term ‘Fluorescence’ on the diamond grading report. The good news is that fluorescence has no significant effects on the value of the diamond, having that said it is important that you should have a good knowledge about it so that you can make your purchase with confidence.
Let’s take a closer look at the term ‘Diamond Fluorescence’ and learn more about it:
- What is Diamond Fluorescence?
Diamond fluorescence can be best described as the diamond’s tendency to release a soft-colored glow when it is subjected to UV (ultraviolet) light. In other words, it is the glowing effect that the UV light has on the diamond. Please note, that 95 percent of the time, the fluorescent glow is blue in color however sometimes it can be yellow or green, but that is very rare.
- What is the Impact of Fluorescence on the Diamond’s Appearance and Structural Integrity?
According to GIA researchers, fluorescence has no major or widely noticeable impact on the appearance of the diamond. And that fluorescence diamonds have the same integrity as those diamonds that have no reaction to ultraviolet rays. Though submicroscopic shifts and substitutions in the structure of the diamond can result in fluorescence but it doesn’t inherently weakens the diamond and neither it is bad for it.
- Two Things Regarding Fluorescence
There are two things that you should know about fluorescence, first that diamonds that fluoresce blue look whiter in daylight and those that fluoresce yellow look lower in color when exposed to UV rays, and second that diamonds that exhibit strong fluorescence have an oily or hazy appearance even in regular lighting conditions which can sometimes affect the value of the diamond negatively.
Although, fluorescence has no significant effects on the purchase of a diamond and it is a personal choice whether to buy a diamond that glows however, to ensure that you make a good purchase without any dissonance it is nonetheless advisable to exercise precaution in buying diamonds with strong fluorescence. Also make sure to focus on factors like the cut of the diamond because it can have more influence on the color of the diamond in comparison to fluorescence.
