Minimize, carat, readability, and shade are the important grading components of each diamond. However, many extra phrases additional describe a diamond and supply perception into its traits. One such time period is diamond fluorescence.
This text will make clear diamond fluorescence and clarify what this time period represents. Furthermore, we’ll talk about whether or not a diamond ought to have fluorescence and supply tips about shopping for fluorescent diamonds.
What Is Diamond Fluorescence?

Diamond fluorescence is the glow these stones can emit when uncovered to ultraviolet (UV) rays. This glow lasts so long as the stone is uncovered to the rays. When the supply of sunshine is eliminated, the fluorescence disappears.
This phenomenon is attributable to sure minerals and parts inside the diamond, and it’s utterly pure. When the UV mild hits the diamonds, the electrons of the aspect get kicked to a better power state. After only a few nanoseconds, the electrons return to their regular state and launch photons within the course of. Our eyes acknowledge these photons and detect them as fluorescence—the extra minerals in a diamond, the stronger the glow, and vice versa.
Not all diamonds are fluorescent, though this can be a widespread attribute. Based on the Gemological Institute of America (GIA), round 25% to 35% of all diamonds are fluorescent to some extent.
When uncovered to UV mild, the commonest shade that fluorescent diamonds exhibit is blue. In uncommon situations, the colour may very well be yellow, inexperienced, or white.
Understanding the Diamond Fluorescence Scale

Each GIA diamond grading report incorporates a component devoted to fluorescence. The official scale has 5 levels: none, faint, medium, sturdy, very sturdy.
None
Should you see “none” in a diamond grading report, it means it doesn’t have fluorescence.
Faint
The diamond is fluorescent, however to not a major diploma. Most observers gained’t be capable of discover faint fluorescence. In some circumstances, faint fluorescence can complement the diamond’s readability and make it appear colorless even when it isn’t.
Medium
Per GIA, the grading reviews of diamonds with a medium fluorescence must also include info concerning the colour. Medium fluorescence normally doesn’t have an effect on the diamond’s look.
Robust
The colour of sturdy fluorescence must be written down on each grading report. Robust fluorescence can generally make the diamond appear oily or hazy, relying on its shade grade.
Very Robust
That is the very best doable diploma of fluorescence. Like sturdy fluorescence, very sturdy can have an effect on the diamond’s look and make it look oily. It doesn’t occur with each diamond with sturdy fluorescence; the impact sometimes is dependent upon the stone’s shade grade.
Per GIA, the fluorescence shade is simply famous if it’s medium, sturdy, or very sturdy. Figuring out a diamond’s fluorescence is completed by evaluating it to a grasp stone with established fluorescence in labs below particular situations.
Is Diamond Fluorescence Good or Dangerous?

Typically, diamond fluorescence is neither good nor dangerous. It’s important to make clear one factor earlier than explaining why some folks could take into account fluorescence a bonus and others a flaw. Fluorescence doesn’t affect the diamond’s inner construction or texture. Diamonds which have fluorescence aren’t any totally different in type than people who don’t.
Furthermore, fluorescence isn’t dangerous to the diamond and may’t harm it. It’s merely a mix of various minerals that work together with UV mild.
Though fluorescence doesn’t truly change the diamond, it will possibly have an effect on how an observer perceives it in some circumstances. To higher perceive why and the way this occurs, we have to talk about one of many 4 Cs: shade.
Diamond Shade

Shade, or the dearth of it, is without doubt one of the important options of each diamond. Diamonds that appear like a drop of water are labeled colorless, and they’re extraordinarily uncommon and priceless. On the opposite finish of the size, now we have diamonds with a yellow tint that lowers their worth.
The GIA shade scale is split into these classes:
- Colorless (D, E, F)
- Close to colorless (G, H, I, J)
- Faint (Ok, L, M)
- Very mild (N, O, P, Q, R)
- Mild (S, T, U, V, W, X, Y, Z)
How Is Fluorescence Associated to Shade?
As talked about, diamond fluorescence isn’t thought of a bonus or a flaw. However, many individuals imagine that it will possibly seemingly improve or lower a diamond’s spark.
For instance, faint diamonds include a slight yellow tint, which impacts their worth. If the diamond has sturdy fluorescence, the blue mild will seemingly lower the yellow tint, making the stone look brighter and extra clear. This occurs as a result of blue and yellow are complementary colours.
In distinction, the looks of diamonds with a D, E, F, G, or H shade grade is commonly “jeopardized” by fluorescence. Robust blue mild could make these diamonds hazy and oily, sometimes making them much less engaging, though they’re colorless or near-colorless.
As you’ll be able to see, it’s inconceivable to say whether or not fluorescence is nice or dangerous. Typically, it is dependent upon whom you ask.
