Fluorescence is the visible light some diamonds emit when they are exposed to invisible ultraviolet uv rays.
Diamond fluorescence gia.
A nonprofit educational resource for the gem and jewelry industry.
Gia studies show that for the overwhelming majority of diamonds the strength of fluorescence has no widely noticeable effect on appearance.
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.

Fluorescence is the visible light some gemstones emit when they are exposed to invisible ultraviolet uv rays.
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.
It is not a grading factor like the gia 4cs color clarity cut and carat weight.
The gia found that 25 to 35 percent of diamonds have some degree of fluorescence.
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.

Fluorescence is the visible light that a diamond emits when it is exposed to the uv rays.
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.
A study performed in 1997 by the gia found that the level of fluorescence has no widely perceptible effect on the color appearance or transparency of diamonds when viewed table down upside down.
Offering online and on campus education diamond grading and identification services and scientific instruments.
In the table up position diamonds of strong or very strong fluorescence appeared to have better color than less fluorescent stones.
This is the same effect the diamond has under the uv rays.
So if you re wondering what diamond fluorescence is think about how u ltra violet light makes your whites look whiter and your blacklight posters glow.
Gia considers diamond fluorescence an identifying characteristic.
The gia grades fluorescence in diamonds as none faint medium strong and very strong.
Diamond fluorescence influences a diamond s color grade fact.
In natural diamonds blue is the most common color of fluorescence but other colors may be visible.
While there are many false and misinformed opinions on whether the presence of fluorescence in a loose diamond is good or bad it s best to consider the gia s in depth long running scientific study of fluorescence.
In assigning a diamond color grade gia examines the gem in a highly controlled viewing environment designed to minimize the influence of fluorescence and to produce an accurate and objective assessment of the diamond s color.
