Natural diamonds have a property known as fluorescence, which allows them to produce brilliance of varying colors when exposed to black light (also known as ultraviolet light). A pure, natural diamond is known to produce a blue glow when exposed to black light. So you're looking to buy a diamond and you start to hear the word fluorescence. What does it mean? Some jewelers tell you it's a good thing, others tell you it's terrible.
Who is telling the truth? To tell you the truth, both may be right and both may be wrong. We'll try to guide you through the diamond fluorescence and get to the bottom of it. Fluorescence in diamonds is the brightness that can be seen when the diamond is under ultraviolet (UV) light. You'll see 30% of diamonds shine under UV light.
When exposed to ultraviolet light, there will be a diamond that will shine in different colors. GIA rates diamond fluorescence as None, Weak, Medium, Strong and Very Strong. So if you're wondering why some diamonds shine under UV light, think about how UV light makes your whites look whiter and your blacklight posters shine. In the same way, some diamonds fluoresce when under UV light. Is diamond fluorescence good or bad? Strong blue fluorescence in diamonds does not always improve diamond color.
Doubts regarding fluorescence in diamonds can arise when buying a diamond. It is important to consider fluorescence when buying a diamond. When fluorescence is used correctly, you can find a magnificent diamond like this one by James Allen. If you ignore fluorescence, you can make a big mistake, like this diamond from Blue Nile. If the diamond only shines when exposed to UV light, then naturally it should only matter if you are someone who spends their days in dark rooms with blacklight lamps.
But the fact is that most diamonds that exhibit Strong Blue Fluorescence appear mildly to severely hazy under normal lighting conditions. If you've done your homework and googled diamonds for fluorescence, you may have read about a certain GIA study that claims that even strong blue is almost always completely undetectable to the average diamond consumer. If the diamonds you are viewing have a strong or very strong blue fluorescence, they will most likely appear hazy, oily, or hazy, and this will also make the diamonds appear less transparent. When comparing diamonds to each other, you will definitely see a difference between a diamond with a strong fluorescence and one with little or no. It's also important to note that this extreme level of haze for a fluorescent diamond is also not typical and is not as common as you might think when talking about diamonds that are H and below. Some studies done on fluorescence make a statement that is correct: Fluorescence generally improves the appearance of color in diamond.
As I suggested in my final recommendation above, if you are buying a diamond with an H color or lower, look for a diamond with medium blue fluorescence. A fluorescent medium blue diamond can even help counteract any yellowish tint diamonds may have and can make them appear much whiter. In effect, this will cause the color and appearance of the diamond to have a higher color grade. Fluorescence can cause diamond to shine and shine brighter than a diamond that lacks fluorescent properties. It will be more affordable, and since you are there in person, you can see for yourself if the diamond exhibits haze or milkiness. Be sure to ask to see the diamond in a variety of different lighting settings, if possible.
Before buying a diamond, get personal buying advice from industry veterans. We'll help you get the best diamond for your money. Take a look at this 2 carat diamond by James Allen and compare it We have visited and reviewed many diamond retailers, online and offline. In the process, we have encountered several sellers of diamond engagement rings. Fluorescence is the glow that is sometimes seen when an object emits visible light. Some diamonds fluoresce when exposed to long-wave ultraviolet (UV) rays from sources such as the sun.
This can cause them to emit a bluish light or, more rarely, a yellow or orange light. Once the UV light source is removed, the diamond stops emitting fluorescence. Fluorescence occurs when a diamond shows a soft glow under ultraviolet (UV) light. This is caused by certain minerals in the diamond. This effect is completely natural and appears in one third of all diamonds.
The phenomenon that causes a diamond to glow under black light is called fluorescence. About 35% of naturally grown diamonds contain this component, and 95% of them glow bluish when exposed to black light. The other 5% can glow in a variety of other colors, including red, yellow, white, green and orange. Understanding the different types of rhinestones can help couples discover if they really want a natural diamond formed by heat and pressure deep in the earth's crust or if an artificial stone is suitable. Knowing how to spot a fake diamond can prevent couples from falling for jewelry scams while ensuring that they can find a charming diamond that fits their preferences and budget. If you've done your homework and googled diamonds for fluorescence, you may have read about a certain GIA study that claims that even strong blue is almost always completely imperceptible to the average diamond consumer. By knowing how to check the authenticity of a diamond, couples can protect themselves from unscrupulous people and find a gem they cherish whether it's a natural diamond or not.
The Disadvantage of Diamond FluorescenceThe disadvantage of having strong blue fluorescence in diamonds is that it can cause them to appear hazy or milky under normal lighting conditions.
This means that although they may appear brighter under UV light they may not look as clear as those without any fluorescence at all.
