wholesale indian fashion jewelry new delhi Most diamonds have fluorescence, generally blue fluorescence. Under long waves of ultraviolet lamps, it can be observed. According to the GIA standard, it is divided into
. , Strong (Strong), Medium (moderate), Faint (weak), and record its color at the same time, at most, Blue (blue) and YELLOW (yellow).
The lightness of the diamond is FAINT, and no longer distinguish between it. Records on the fluorescent response on the certificate are helpful for distinguishing diamonds.
The fluorescent levels of diamonds have a great influence on the price of VS -level diamonds with a color of D -G more than 50 points. Generally, weak fluorescence does not have much to do. Middle fluorescence will affect about 7%-10%. The greater the impact of the high color, which can reach 30 % or even more. Especially strong fluorescence is basically about 35 % lower than the price without fluorescence. Generally, the price of diamonds of about 1-2 carats is greater. The colorless color produces a hazy feeling (more clear under 10 times), which affects the transparency of high -color diamonds. For diamonds lower than J -color, although fluorescence can make the diamond white, but the price will still be low. 5 % -10 %, the color is as low as m, and the fluorescence has basically no effect on the price. Those who are less than 20 points in small diamonds basically do not affect the price. There is also a certain price effect. Because the National Gem Testing Center does not conduct a classification of fluorescence, most of the diamonds sold on the market do not specifically explain, except for international certificates. However, because most of the diamonds are imported, the price follows the price standards and market demand of the international market. Generally speaking, the price of the domestic certificate diamond is not affected by fluorescence. The color is prevailing, and it is not affected by its fluorescent response. The fluorescent response has a strong diamond, which has a poor transparency. It seems that it seems to be like soapy water, which is beautiful, but it does not indicate the certificate. This point must be paid attention to. However, although the fluorescent response is strong, the diamond color is still clear, so it cannot be discussed.
gold jewelry pendants wholesale Looking at the picture, you can't see the effect. Generally, you can argue whether the diamond certificate is fluorescent through the diamond certificate. When you buy it, you can also put forward your request to the salesperson. Without fluorescence,
faint refers to weak fluorescence.
