The influence of fluorescent grade diamond for diamond prices

We all know that diamond prices determined by the 4 c standard of diamond, the diamond clarity, color, cut, and weight. But in diamond quotation with the diamond quality can be measured in a we haven't heard of terminology, it is a diamond fluorescence. Diamond fluorescent really mean? Fluorescent diamonds and how to affect the price of diamond? Diamond fluorescence is blue diamond under intense ultraviolet radiation from the diamond level of fluorescence to measure the intensity of blue light. Admiral international diamond fluorescence level is divided into: almost no, can't see, weak, medium, blue, and the strong, in the case of other same quality, the higher level of fluorescence the cheaper price. Among consumers with a saying 'there are more white fluorescent diamonds', it is, but does not represent a diamond with fluorescence, the better. Diamond color level below J color, there are fluorescent diamonds are more white, but it does not increase the price drop. The diamond fluorescent grade for diamond prices affect how? Diamond fluorescent grade for diamond prices according to the size of the diamond, the influence of the quality. Diamond is larger, the higher the quality, the greater is the impact on the fluorescence for diamond prices. Diamond size below 20 points, diamond fluorescent basically does not affect the price, so if you are don't have to consider diamonds to buy 20 points in the fluorescent grade. Diamond size in 20 to 50 points, and diamond studs are registration above VVS, fluorescent diamonds will affect the price of diamond. D - G color, more than 50 points and clarity in VS above, diamond silver for price effect is more obvious. Generally weak fluorescence can affect prices by about 5%, moderate fluorescence affects 7% to 10%, the greater the strong fluorescence effect on increasing high color, can reach 30% or more. If size in more than one carat diamond, diamond fluorescence effect on the price is bigger, because the fluorescence will affect the transparency of diamonds, affect the look of a diamond. We can draw from the on, only to achieve a certain quality of diamond prices are influenced by diamond fluorescence, so for us to average consumer, we don't have to care about the diamond fluorescent grade. Diamond collection or investment, but if you do we'll alert.
