Does diamond fluorescence affect wearing? How to treat the fluorescence grade of diamonds? Generally speaking, the quality grade of diamond is determined by 4C, but there is an indicator of diamond fluorescence reaction on the certificate of GIA Gemological Institute in the United States, which many consumers don't know very well. Does diamond fluorescence have any effect on consumers who wear diamond jewelry? What should we think about the fluorescence grade of diamonds? Let's follow the diamond experts of Escape Diamond Jewelry Network to learn about diamond fluorescence. Whether there is fluorescence or strong fluorescence depends on your hobby level, that is, if you like it, you can buy it with fluorescence, and if you don't like it, you can buy it without fluorescence, but they don't affect the value of the original stone. Fluorescence is a natural indicator, but it does not affect the value of diamonds. The value of a diamond depends only on 4C, that is, color, clarity, size and cut. The remaining indicators are for reference only. It can be said that under the condition that 4C meets your selection premise, the fluorescence selection of loose diamonds is not considered. A loose diamond with strong and weak fluorescence. The international level from low to high resolution is GIA standard: none, weak, medium blue/medium yellow, strong blue/strong yellow, or IGI standard: none, very weak. Of course, not all diamonds have fluorescence, but most diamonds do have a little fluorescence. The fluorescence index should be written in the international testing of diamonds, and there is no special mark on the domestic certificate. Bare diamond fluorescence refers to the intensity of colored light such as blue light or yellow light emitted by diamond under strong ultraviolet light. In other words, we can't see it in natural light. Unless there are diamonds with strong fluorescence in the summer sun with strong ultraviolet rays, we can see the existence of fluorescence with the naked eye. Except in this case, fluorescence has no effect on what we wear. Does diamond fluorescence affect wearing? How to treat the fluorescence grade of diamonds? To sum up, diamond fluorescence is only a feature of diamond, which has no direct impact on the price of diamond, but only on the psychology of consumers pursuing perfection. When actually buying diamonds, you only need to pay attention to the 4C index of diamonds.
