Diamond Fluorescence

Years ago, when the diamond was crystallizing, it would give the diamond a phenomenon known as fluorescence if the element boron were present. These diamonds would glow or radiate a blue color in the UV light. That only means Diamond fluorescence refers to the effect of ultraviolet light on a diamond.

Fluorescence in a diamond can be treated as a positive or negative factor depending on the diamond’s color. For instance, in colorless diamonds, basically, that is a negative factor, while in near colorless diamonds, it is a positive factor. Do you know 4cs of a diamond?

Grading Fluorescence on Diamond

The classification of fluorescence varies from faint through faint to medium, heavy, and very strong. Often a diamond with strong or very strong fluorescence may have a milky appearance, but less than 2% of diamonds with a strong or solid fluorescence grade exhibit this.

According to GIA, studies have shown that the strength of fluorescence has no strong effect on the appearance of diamonds. Even under standard lighting conditions, some diamonds with exceptionally high fluorescence look oily or cloudy. The diamond is then given a dull look.

Checking the GIA certificate is the best way to guarantee the fluorescence of your gem. It is clearly stated as faint, medium, strong, or very strong. Judge this natural gemstone based on personal preference by considering its own visual qualities and features.

Fluorescence Effect on Diamond

Note that outside of the UV lighting environment, you cannot make a visual distinction between fluorescence and non-fluorescence diamonds. However, the presence of fluorescence has a great effect on these diamond pricing. They trade at a 10-15% discount in the market and can go higher with more colored fluorescence diamonds.

Another big effect of diamonds with stronger fluorescence is the change in appearance, which can be cloudy, foggy, or even oily. They are not desirable in any color grade and become a serious concern when it comes to selling. Therefore, they always significantly have fewer purchase prices as well as resell value.

How Fluorescence Affects Price

The effect on price varies depending on the degree of fluorescence, diamond color, and clarity. Fluorescence diamond affects the great and makes it look lifeless. Here fluorescence is neither good nor bad as it enhances the diamond’s appearance.

For example, an E-color diamond of VS1 clarity and Strong Fluorescence will tend to sell for 3-5% less than a like diamond with no fluorescence. fluorescence might cause a diamond to look unduly dull or oily. In others, it might not impact the visual appearance. As the appearance of fluorescence affects the price. As a result, the customers who lean towards higher clarity tend to be more adverse to the reality of fluorescence.
