Natural diamonds have a property known as fluorescence, which allows them to produce a 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 this type of light. But what does this mean for diamond buyers? Is diamond fluorescence good or bad and does it affect the value of diamonds?To understand diamond fluorescence, it's important to know that 30% of diamonds will shine under UV light. When exposed to ultraviolet light, diamonds can fluoresce in different colors.
The Gemological Institute of America (GIA) rates diamond fluorescence as None, Weak, Medium, Strong and Very Strong. Strong blue fluorescence in diamonds can improve the appearance of color in diamond. If you're looking at diamonds with an H color or lower, look for a diamond with medium blue fluorescence. This can help counteract any yellowish tint the diamond may have and make it appear much whiter. However, it's important to note that strong or very strong blue fluorescence can cause a diamond to appear hazy or oily under normal lighting conditions. When buying a diamond, it's important to consider fluorescence.
If you ignore it, you could make a big mistake. Be sure to ask to see the diamond in a variety of different lighting settings and get personal buying advice from industry veterans. This will help you get the best diamond for your money. It's also important to know how to spot a fake diamond. Knowing how to spot a fake diamond can prevent couples from falling for jewelry scams while ensuring they get the real deal.
