Fluorescence chart for diamonds
Diamond Fluorescence. Fluorescence refers to a diamond's tendency to emit a soft colored glow when subjected to ultraviolet light (such as a "black light"). Roughly 30% of diamonds fluoresce to some degree. Colorless (D-F) fluorescent diamonds sell at up to a 15% discount since the fluorescence is perceived as a defect. The fluorescence effect is present in over 30% of diamonds and is an important consideration when buying a loose diamond. When UV light strikes a diamond with fluorescent properties, the stone emits a glow. Fluorescence refers to the discharge of light by a diamond after it is subjected to electromagnetic radiation (e.g. ultraviolet light). Some common sources of UV radiation include black lighting from night clubs, fluorescent bulbs and natural sunlight. When trace amounts of elements such as boron, Fluorescence is the reaction of the diamond when exposed to ultraviolet light which is invisible to the human eye. While some diamonds display a characteristic fluorescence color, most do not react to UV at all. Please read the chart below carefully as we have tried our best to summarize most relevant information about diamond fluorescence in it to save you time. Please also check the subsequent chart for how much discount you should get in a given fluorescence range and how color plays a role in determining such discounts. The opposite is true for diamonds with higher color grades: diamonds in the D to H color range with a bluish fluorescence are often considered less desirable by the trade. Some believe that a bluish fluorescence may cause a hazy or oily appearance in these diamonds, but only if the fluorescence intensity is very strong. The most common fluorescence color is blue which applies to around 98% of all diamonds with fluorescence. There are however white, yellow, green, and even pink fluorescence. Ultimately, the color is decided by the physical make-up of the diamond’s inner atomic structure.

Diamond Fluorescence Diamond fluorescence is the soft glow (usually blue) a diamond produces under ultraviolet light. This visual effect is natural in 1/3 of all diamonds in the world. Frequently, the blue fluorescence doesn’t negatively affect a diamond’s outlook. Fluorescence is when a diamond shows a soft glow under ultraviolet light (usually blue). This is caused by certain minerals in the diamond. This effect is totally natural, appearing in one third of all diamonds. Usually, fluorescence doesn't actually cause any negative effects on the appearance of a diamond. Diamond Color Chart - Beyond the D-Z Diamond Color Scale. The most detailed and practical guide on the web explaining the nuances between all different color diamonds, prices, dos and don'ts.At the end - you'll know which is the best diamond color for you! Medium Blue Fluorescence. Diamonds in this level of fluorescence are usually not hazy. As I have also described in my post about diamond color, you should consider medium blue fluorescence for H-K color graded diamonds.. Since the glow is usually blue, and blue complements yellow, diamonds with H-K color can appear whiter. DIAMOND GRADING CHART. Every diamond certified by the GIA undergoes a thorough, independent evaluation. Here you will learn how GIA diamond grades are established, and how those grades affect the diamond's price. Each of the four C's (Carat Weight, Cut, Color, Clarity) is accompanied by a diamond chart illustrating the differences between grades.
Fluorescence in diamonds refers to how a diamond responds when subjected to ultra-violet light. Ultra-violet light is what makes your whites look whiter, your teeth bright white, and your black-light posters glow. Some diamonds, when they are exposed to ultra-violet light and other lighting conditions,

Some diamonds, when they are exposed to ultra-violet light and other lighting conditions, Diamond Fluorescence Chart / Grading Reports Many grading reports confirm whether or not a diamond fluoresces, and if it does, the level of the effect - none, faint, slight, moderate, strong or extreme. The strength of fluorescence in diamonds is described in the following chart by specific abbreviations: UV diamond fluorescence occurs in about 35% of colorless (white) diamonds and can be faint or very strong. (Fluorescence is a type of glow that occurs almost immediately after exposure to UV light). In most cases, diamonds fluoresce blue. This cancels out the slightly yellowish color in most diamonds, resulting in a whiter appearance in sunlight. While fluorescence does cause diamonds to look milky in some cases, the majority of blue fluorescence diamonds are perfectly fine. In fact, their appearance and transparency will look identical to non-fluorescent diamonds. Because many people view it as a “defect”, diamonds with fluorescence are harder to sell as well. Fluorescence Grading. Diamond fluorescence is graded on a scale established by GIA. Please note that fluorescence seems to visually impact the diamond in about 1% or less of all cases. To reduce the possibility, With Clarity does not carry Very Strong fluorescence graded diamonds. Fluorescence is an invisible glow that a diamond emits under UV rays. It can be a positive and negative factor in a diamond depending on the color of the diamond. In colorless diamonds, it is generally a negative factor whereas in near colorless diamonds, it is a positive factor.
