Education Understanding Diamond Fluorescence Is diamond fluorescence good or bad and affects the value of diamonds? 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? Who is right? 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 (i.e. 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 fluorescence improve diamond color? Doubts Regarding Fluorescence in Diamonds Should I buy a diamond that exhibits fluorescence? When buying a diamond, it is important to consider fluorescence. 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. On the surface, nothing seems to make sense. 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.
About a quarter of all diamonds have some measure of fluorescence; however, only a very small part has so much that it actually affects appearance. When the fluorescence is a normal amount, or in most cases, the color appears blue. But in the rare cases where it causes the diamond to appear yellow or white, the fluorescence is seen as negative. A surprisingly large percentage of diamonds (25 to 35%) fluoresce to a certain extent.
GIA and other laboratories such as IGI and GCAL evaluate the fluorescence of a diamond by its intensity, ranging from zero to weak, medium, strong and very strong. Similar to color, fluorescence is compared to a set of masterstones in the laboratory. Diamonds glow with black light due to a phenomenon called fluorescence, and approximately 35% of natural diamonds exhibit some degree of this effect. In nature, the presence of certain chemical impurities within the diamond composition triggers this brilliant effect in the presence of an ultraviolet light source.
The truth is that brilliance and brilliance are determined by the quality of the cut and not by whether the diamond has the ability to shine with black light. The downside to buying a diamond with fluorescence is that you can end up with a hazy or hazy looking diamond. In the above 2 examples, both diamonds are well-cut diamonds with similar grades of carat weight, D color and VVS1 clarity. We have a large selection of premium cut GIA diamonds specializing in diamonds of 1.5 carats or more.
But honestly, the best way to approach fluorescence when choosing your diamond is the same way you approach other diamond characteristics, such as shape. If you're buying a natural diamond, chances are you've learned that between 25 and 25% of natural diamonds fluoresce i. Fluorescence in diamonds is the brightness that can be seen when the diamond is under ultraviolet (UV) light (i). Another practical benefit of buying a diamond with fluorescence is that it can help improve the color appearance of diamonds in the lower color ranges.
First, you can check the authenticity of the diamond you have by matching the inclusions to the clarity graph of the diamond. Use a variety of methods, such as using a Presidium diamond tester and magnifying the stone to look for characteristics other than diamond formation. If, of course, you buy a diamond in person and not online, then the best thing for you is to specifically order a diamond with a strong blue fluorescence. In general terms, diamond fluorescence is blue, but from time to time, a diamond is seen to fluoresce another color, such as yellow.
