Naked diamond fluorescence is divided into five grades of NON (none), f (weak), MED (medium), S (strong), VS (strong). The price of diamonds above the VS level above is greatly impact. Middle fluorescence will affect the price of about 5%-10%, and the strong fluorescent is 30%or even more cheaper. Especially strong fluorescence is basically about 35%lower than the price without fluorescence. 2 The stronger the fluorescence, the greater the colorless color, the greater the colorless color. Under the light, it will produce a hazy feeling (more clear under 10 times), which affects the brightness and transparency of high -color diamonds. For diamonds lower than J -colors, although blue fluorescence can make diamond white, the price will still be 5 % -10 % lower. Basically, small diamonds do not affect the price below 20 points. There are certain price effects above 20 points. The domestic testing center does not comment on fluorescence because of the fate of the testing level, but because most of the diamonds belong to imports, the price is changed to follow the price standards of the international market. Therefore, many fluorescent diamonds and selling the same price without fluorescent diamonds are a great loss for consumers.
3 In order to ensure that your diamond price is worth it, if your diamonds must ask the fluorescent level of the seller diamond more than 20 points, and at the same time, after receiving the goods Compare the transparency of the diamond. If the transparency of diamonds will become much worse under strong light, then your diamond is likely to be strong fluorescence. If the cobalt stone has strong fluorescence, it will look fog under light.
The take a good look. If the fluorescence is strong, it will not only affect the fire color of the diamond, but also the price is not too high. It you can go to Handan Diamond Baby to see. When you buy diamonds in Diamond Baby, you really learned a lot of knowledge.
No fluorescence is a very good diamond. Is there only fluorescence that only affects the price and will not affect the aesthetics.
British light is best
