Fluorescence is the phenomenon where light can be emitted by a substance after it has been excitation by radiation or mechanical energy, usually with shorter wavelengths than those used to generate the original electromagnetic spectrum. This phenomenon normally occurs in the ultraviolet spectrum and less frequently in the visible spectrum.Diamonds can emit different types of visible light, depending on the type of radiation used to excite them. Most often, the fluorescence takes place in visible light or ultraviolet.
What Does Fluorescence Mean in a Diamond?
When the diamonds are exposed to UV, the stones will emit visible light in the blue portion of the spectrum. The intensity of this fluorescence depends on the color of the diamond and can be used to distinguish between different types of diamonds.
The diamonds with blue fluorescence are often called blue diamonds, while the ones that do not have the fluorescence are called brown diamonds. In addition to these different colors, diamonds can also emit different types of visible light depending on their state. For example, when they are cooled to low temperatures – such as during a diamond’s natural crystallization process – the stones can emit orange light.
The diamond fluorescence is based on the presence of impurities and the internal crystal structure of the diamonds. The thermal infrared emission from diamonds is associated with their crystalline structure, while in the case of x-rays, it is due to atomic structure. For this reason, for the same type of diamond, there will be different fluorescence depending on the type of radiation used to excite it.
Is Diamond fluorescence a good or bad thing?
The answer will depend on the buyer’s perception and should be evaluated from a specific perspective. From the majority of perspectives, a blue diamon (the most valued type of fluorescence) is considered a good thing, because it gives the diamnd more fire and more value. However, other buyers think that this phenomenon is not an advantage and do not want to buy a blue diamod.
Does fluorescence make a diamond more valuable?
Diamonds’ fluorescence is a phenomenon and has nothing to do with the value of the stone.The value of a diamond isdictated by its carat (weight, size), cut, and clarity. If the diamond has these qualities, there is no reason why it should not have fluorescence. Many diamonds have fluorescence, but not all; it is a matter of chance. The chance is that the stone will be affected by some type of radiation. Fluorescence is not a flaw, but a natural phenomenon. If this occurs in your diamond, it is not something that should make you concerned. The fluorescence has nothing to do with the quality of a diamond and can be
considered part of its beauty.
Do all diamonds have fluorescence?
The answer to this question is no. There are different types of diamonds with fluorescence. Of all the diamonds only about 30% have fluorescence, and even fewer of those have blue fluorescence in a good light.
Diamond Fluorescence scale
This diamond is not affected by any type of radiation and therefore has no fluorescence.
Faint – The stone has a little blue fluorescence under UV light and it is the lowest value on the scale.
Medium-The fluorescence index is between low and high. The stone has a medium blue fluorescence under
The stone has a strong blue fluorescence under UV light. It is the highest value on the scale.Whether you want a diamond with fluorescence or not, it is important to know from whom you are buying the diamond. www.rarecarat.com is the leading online diamond marketplace for both natural and lab-grown diamonds and engagement ring settings.
