When we speak of Diamond Fluorescence, we are referring to the diamonds tendency to emit a soft
colored glow when subjected to ultraviolet light (such as a "black light"). Fluorescence is a form of
illumination that is created when a diamond is exposed to low or high wave ultraviolet radiation.
Faint or medium fluorescence will rarely affect a diamond's appearance. Usually fluorescence is
unnoticed by the human eye in ordinary light. Fluorescence can cause a diamond to appear less clear
or slightly hazy if the diamond exhibits very strong or extreme fluorescence. When selecting your
diamond it is best to choose a diamond that has no fluorescence or faint to moderate fluorescence.
N – NONE
This diamond do not have any fluorescence
F – FAINT / VERY SLIGHT
This diamond have weak fluorescence, not a significant influence on color
M – MEDIUM / SLIGHT
This diamond have average fluorescence, small influence
S – STRONG
This diamond have strong influence, substantial color influence
VS – VERY STRONG
This diamond have very strong influence, substantial color influence
When we speak of Diamond Fluorescence, we are referring to the diamonds tendency to emit a soft colored glow when subjected to ultraviolet light. Different diamonds emit different colors, examples of which are listed below
This is another parameter, which has been found of importance in determining the exact purity of the diamond. The amount of light that the stone reflects and the type of light that is emitted by the stone determine luster of a diamond. Luster refers to the quality of a surface in reflected light. The luster of a diamond is usually described as adamantine luster.
L1 – VERY GOOD
This diamond has very high quality reflection and emission of light.
L2 - GOOD
This diamond has high quality reflection and emission of light
M1 - LIGHT MILKY
This diamond has low quality reflection and emission of light
M2 – MEDIUM MILKY
This diamond has very low quality reflection and emission of light.
M3 – HEAVY MILKY
This diamond has very very low quality reflection and emission of light
