Diamond Fluorescence and Structure

A diamond’s ‘medium’ or ‘strong’ degree of fluorescence can sometimes be seen on the stone’s grading report. Should you worry about it? Let us look into the significance of the grading and the possible influence on the diamond’s appearance in more detail.  


Essentially, fluorescence is the colour effect that ultraviolet light has on diamonds. Under blue or ultraviolet light you will notice that the white colours on your own clothes will appear to be glowing. A similar effect can be seen with diamonds when they are exposed to ultraviolet rays. Here at La Vivion you can find out more about this interesting feature of the precious brilliant stones.


How Common Is Fluorescence In Diamonds?


Fluorescence is quite a common phenomenon, occurring with approximately one fourth to over a third of overall GIA-certified diamonds, which display a certain degree of it. Despite this, only 10% of such diamonds exhibit a level of fluorescence that might influence its appearance. Usually, the strength of fluorescence listed in gem laboratories is listed as medium, strong, or very strong.


The majority of the diamonds that display a degree of fluorescence show up as blue under UV rays. The blue colour complements yellow, one of the most popular shades in these precious stones. Ultraviolet light can make these diamonds look colourless or even glowingly white.  


The Influence Of Fluorescence On The Diamond Structure


Studies which were carried out by GIA show that fluorescence has no noticeable effect on the diamond’s overall appearance. In the research the observers preferred diamonds with medium to strong fluorescence. However, there are rare instances when diamonds that have a high level of fluorescence look oily, or hazy.


Despite this, when it comes to the structure of the precious stone, the integrity of diamonds with and without fluorescence is the same. Things like microscopic shifts in the structure may prevent fluorescence or cause it, but it has no effect on the stone itself.


Shopping For Diamonds: Is Fluorescence A Factor?


When you shop for diamonds, you should take your own preferences into consideration. Treat it as if it were a feature of the stone, just like the colour or the shape. The main idea is to consider everything and look into the diamond as a whole.


Other factors have a lot more influence on the diamond’s appearance than fluorescence. Things like the cut, shape or clarity come into play, as well as the light source and even your outfit. Thus, it is not a significant feature of the precious stone and has no influence on its strength or general appearance.
