Have you ever wondered why your diamond is glowing in a purple color under black light?
Some diamonds glow in different colors like a blueish purple color under black light because of a phenomenon called fluorescence.
Do you know what is black light? The black light can also be called UV light or ultra violet light.
It is just a lamp that emanates ultraviolet light. The ultraviolet light emanated by the lamp is not visible to the naked eye.
Many people often get confused about the difference between ultraviolet light and black light but actually, there is not much of a difference and they are the same thing.
The black light can illuminate the fluorescence present in the diamonds with ultraviolet light.
That makes some natural diamonds glow in a variety of different colors in the presence of ultraviolet light.
If you are pondering whether you should be buying a diamond with fluorescence or is it a bad thing then you need not worry.
If you want to buy a diamond with fluorescence then go ahead and buy it without hesitating too much.
Fluorescence in diamonds can even improve and enhance the appearance of your diamond.
Whether you should be buying a diamond with fluorescence or not depends mainly on your taste.
The bad thing about a diamond with fluorescence is that it can get a foggy and cloudy look but it is very rare.
However, many people think that the shine and sparkle of diamonds with fluorescence get dull and that diamonds with fluorescence are not durable but they are all myths and there is proof that it is true.
Why is My Diamond Glowing Purple Under Black Light?
The answer is simple. It is because of a phenomenon called fluorescence present in diamonds that makes diamonds glow in different shades of blue, purple, green, and sometimes even red and yellow under UV light.
At least 30% of diamonds have fluorescence. There are different levels of fluorescence present naturally in diamonds. More specifically there are 5 types of diamond fluorescence.
The first type of diamond fluorescence is None Florescence. This is the type of diamond that has no fluorescence and thus they are the type called none florescence.
The second type of diamond fluorescence is called Faint Fluorescence. This is the type of diamond that has very little fluorescence so this type is called faint fluorescence.
The third type of diamond fluorescence is called Medium Fluorescence. As indicated by its name, this is the type of diamond that has a medium level of fluorescence.
The Fourth type of diamond fluorescence is called Strong Fluorescence. This is the type of diamond with strong fluorescence but not too strong.
The fifth type of diamond fluorescence is called Very Strong Fluorescence. Now, this is the type of diamond with very strong fluorescence. This is the last type and it has very strong fluorescence.
If your diamond is also glowing in a shade of purple under black light or UV light, it is very natural as the diamonds with fluorescence glow in a blueish purple color or another color under UV or black light.
Do Real Diamonds Glow Under Black Light or UV light?
It is indeed true that real and natural diamonds with fluorescence glow under UV light or black light and that natural diamonds have fluorescence so they glow under UV light.
Still, we should not be deciding whether a diamond is real or not based only on the fact that it glows under black light or UV light.
Not all natural diamonds have fluorescence. Only 30% of the natural diamonds are known to have a phenomenon called fluorescence.
So, don’t worry if your diamond is not glowing under UV light. The diamond you own may be natural but it does not have fluorescence so it is not glowing when exposed to black light or UV light.
Do Fake Diamond Glow Under Black Light?
Now that we know natural diamonds glow under black light or UV light, it makes us think if fake diamonds can also glow under black light or not.
While 30% of the natural diamonds can glow under black light, fake diamonds cannot glow when they are exposed to UV light or black light.
However, the lab-created diamonds can glow under black light too like the natural diamonds. Lab-grown diamonds are the type of fake diamonds.
What Colors Do Diamonds Glow Under a Black Light?
When natural diamonds with the property of fluorescence are exposed to black light or ultraviolet light, they can glow in many different colors.
The most common color is blue as most diamonds glow in blue color when you exposed them to UV light or black light. Other than blue, diamonds can glow in yellow, green, purple, and red colors too.
