Many consumers have some misunderstanding about diamond fluorescence. They think that fluorescent is not a good diamond, or that diamond fluorescence will affect the human body, such as computer radiation. Now let Xiaolan Xiaobian unveil the diamond fluorescence for everyone. secret.
1. What is diamond fluorescence?
The fluorescent Fluorescence indicator refers to the intensity of colored light such as blue or yellow light that a diamond emits under intense ultraviolet light. That is to say, under natural light, we can't feel it, unless there is a strong fluorescent diamond in the strong summer sun, we can feel the presence of fluorescence. Except for this situation, fluorescence has no effect on our wearing.
Second, do natural diamonds have fluorescence?
Not all diamonds have fluorescence, but it is true that most diamonds have a little fluorescence. Internationally, diamonds are written to be fluorescent indicators, and there is no special label on the domestic certificate.
Third, how to distinguish between the color and strength of fluorescence?
Fluorescence is not all blue, and the fluorescence of diamonds is blue, yellow, orange, pink, and so on.
The fluorescence of diamonds is strong and weak. The international level from low to high is GIA standard: none, faint, medium blue, medium yellow, strong blue. ) /strong yellow (strong yellow) and other levels, or IGI standard: none, no slight, slight, strong, and so on. This is explained in every international certificate provided by GIA, you don't have to worry about needing to distinguish it yourself.
4. Does fluorescence affect the value of diamonds?
Although fluorescence is a natural indicator, it does not affect the value of diamonds. The value of a diamond depends only on 4C, which is color, clarity, size and cut. Other indicators are for reference only. The choice of fluorescence can be said that when 4C meets your selection criteria, you don't have to think about it. Whether there is fluorescence or strong fluorescence depends on your preference, that is, if you like to buy fluorescent, you can buy it without it, but they do not affect the value of diamonds. The world's famous blue diamond, Hope, is a diamond with Strong Blue.
5. Does the fluorescence have radiation, does it have an impact on health?
In fact, this is a big misunderstanding, and I don’t know who first opened this rumor. The principle of fluorescence is that the diamond is exposed to ultraviolet light, and because of the nitrogen atom, the ultraviolet energy is absorbed by it and immediately re-emitted at a lower or longer wavelength. The lower energy fluorescence we see is blue. Fluorescence, which is not radioactive, has no radiation, and has no effect on health.
6. Does the diamond with or without fluorescence look different?
A blue-fluorescent diamond will look whiter at the same color level as a non-fluorescent diamond. The blue light will be a little more intense when it is fired, but it depends on the size of the diamond and the intensity of the fluorescence. When the international certificate is opened in diamond color, it is necessary to deduct some blue fluorescent whitening scores, that is, if both diamonds are F color and a Strong Blue fluorescence is a certificate of the same international institution, it is very The big possibility is that the original color of the diamond with fluorescence is higher than the other one without fluorescence, but the fluorescence of yellow is just the opposite.
