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 black 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 the impact of fluorescence on diamonds, it's important to know how it is rated. The Gemological Institute of America (GIA) rates diamond fluorescence as None, Weak, Medium, Strong and Very Strong.
About 30% of diamonds will shine under UV light. When exposed to ultraviolet light, some diamonds will shine in different colors. So is diamond fluorescence good or bad? Generally speaking, strong blue fluorescence can improve the appearance of color in diamonds. If you are buying a diamond with an H color or lower, look for a diamond with medium blue fluorescence. This can help counteract any yellowish tint diamonds may have and make them appear much whiter.
However, if the diamond has a strong or very strong blue fluorescence, it may appear hazy, oily or hazy under normal lighting conditions. It's also important to note that this extreme level of haze for a fluorescent diamond is not typical and is not as common as you might think when talking about diamonds that are H and below. Before buying a diamond, get personal buying advice from industry veterans to ensure you get the best diamond for your money. 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. Be sure to ask to see the diamond in a variety of different lighting settings, if possible. This will help you determine if the diamond exhibits haze or milkiness. In conclusion, understanding the different types of rhinestones can help couples discover if they really want a natural diamond 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. By knowing how to check the authenticity of a diamond, couples can protect themselves from unscrupulous people and find a gem they cherish.
