What Is a None Fluorescent Diamond?

Do you want to know what diamond fluorescence None means? What is the value of a None fluorescence diamond? Jemmia Diamond will answer everything for you right in this article.

What does diamond fluorescence None mean?

Fluorescence None is one of the fluorescence levels of a diamond. When we shine a light ray into a diamond, it creates scattered light. A fluorescence spectrum appears, but we cannot see it with the naked eye. This phenomenon is called diamond fluorescence none.

Diamonds with None fluorescence spectrum usually appear in colorless diamonds. These are diamonds with color grades from J – D.

None fluorescence expresses perfect beauty in every facet of the diamond. At the same time, it also affirms the enduring value of the gemstone.

The meaning of diamond fluorescence

The fluorescence spectrum is used as a factor for identifying diamonds. Scientists and jewelers will perform diamond fluorescence testing in the laboratory. We will identify diamond fluorescence visually.

Fluorescence reflects very realistically the color and color-changing tendency of each diamond. Light yellow diamonds will have very strong fluorescence. But for colorless diamonds, the fluorescence level is very low and may be absent. Because fluorescence affects the color of the diamond.

In fact, fluorescence intensity only affects the beauty of a diamond to the naked eye. We will notice the fluorescence light shining brilliantly and beautifully. According to evaluations, the most perfect value belongs to diamonds with None fluorescence. Along with that, fluorescence also expresses the enduring value of the diamond. The lower the fluorescence level, the longer it will last.

Fluorescence levels in diamonds

Researchers have divided diamond fluorescence into 5 levels. Each level corresponds to a different fluorescence intensity and value.

• Very strong – Extremely strong fluorescence
• Strong – Strong fluorescence
• Medium – medium fluorescence
• Faint – Faint fluorescence
• None – no fluorescence

The influence of fluorescence on the color of a diamond is very significant. It can make the diamond look whiter and brighter, or it can make it appear cloudy in color. This is the two-sided effect of diamond fluorescence.

Very strong or strong fluorescence will help diamonds in the light yellow subgroup I – M appear whiter. This light yellow diamond is increased in value.

As for diamonds in the D – H color group with fluorescence, a hazy and slightly blue appearance will occur. The value of diamonds in the D – H color group will gradually decrease according to the intensity.

How much does a None fluorescence diamond cost?

The phenomenon of diamond fluorescence affects the color of the diamond. It also has very little impact on pricing. The value may increase or decrease depending on the GIA 4C standards.

Once you understand what None fluorescence diamond means, you will be able to analyze diamond prices in the best way.

In the first case, D – H color diamonds and clarity from IF – VS. The value of the diamond will be inversely proportional to the fluorescence intensity. That is, the stronger the fluorescence, the more the diamond's value will decrease.

None fluorescence has the least effect in reducing the diamond's value.  The value of diamond types will decrease from 3%  to 15% in this case.

In the second case, diamonds with lower color grades may increase or decrease in value. The diamond price will increase by 2% when there is blue fluorescence. At the same time, the diamond price may also decrease from 5% to 10% if there is yellow fluorescence.

The value of a perfect diamond will always be the highest. That is when the gemstone has a color grade from D – J and None fluorescence. Flawless perfect beauty is what we get in this diamond classification.

Above are the answers about what diamond fluorescence None means. The value of None fluorescence will depend on the color and clarity of the diamond. If you want specific information, please contact and receive consultation from Jemmia Diamond via hotline 0838 353 333.
