Gia Diamond Fluorescence Scale

The less color a diamond has the higher the grade it will receive.

Gia diamond fluorescence scale.

The gia color scale classifies diamonds on a color scale that starts at d which means colorless to z which is a light brown. Fluorescence is an invisible glow that a diamond emits under uv rays. Gia diamond grading reports and diamond dossiers describe a diamond s fluorescence by its intensity none faint medium strong and very strong when compared to masterstones used in the lab. There is a master set of diamonds that are used by the gia to compare each diamond on the color scale.

Easily run gia certificate verifications from your custom vault dashboard to see a gia check anytime. Please note that fluorescence seems to visually impact the diamond in about 1 or less of all cases. The color of the faint fluorescence can be anything. Evaluate the clarity scale.

On a gia diamond grading report fluorescence refers to the strength or intensity of the diamond s reaction to long wave uv which is an essential component of daylight. Another mineral graphite also contains only carbon but its formation process and crystal structure are very different. According to the gia fluorescence is the visible light that a diamond emits when it is exposed to the uv rays the strength and intensity of fluorescence determines its diamond fluorescence gia certification grade. Diamond color and fluorescence combinations.

Gia issues the diamond grading report for loose natural diamonds only weighing 0 15 carats or more. The gia found that 25 to 35 percent of diamonds have some degree of fluorescence. The light emitted lasts as long as the diamond is exposed to the ultraviolet source. It delineates how much strength the diamond has against the long wave uv light.

It can be white yellow red or blue but i would say that it is most likely going to be blue. Gia scale uses the following grades to identify fluorescence. According to gia fluorescence is the effect that ultraviolet uv light has on a diamond. Unfortunately gia does not note the color of the fluorescence unless the diamond has medium strong or very strong intensity of fluorescence.

The gia diamond grading report includes an assessment of the 4cs color clarity cut and carat weight along with a plotted diagram of its clarity characteristics and a graphic representation of the diamond s proportions. If the fluorescence is medium strong or very strong the color of the fluorescence will be noted. Learn more about how gia diamond grading reports describe diamond color and fluorescence. To reduce the possibility with clarity does not carry very strong fluorescence graded diamonds.

Diamond fluorescence is graded on a scale established by gia. Certain diamond color grades pair well with faint or medium fluorescence and our experts will let you know if your diamond exhibits the perfect combination of color and fluorescence grade.
