Diamond fluorescence can affect the quality of diamonds. Diamond fluorescence refers to the visible light emitted by diamonds under ultraviolet light irradiation, which has a certain impact on the flame color. Under the same level of other parameters, the stronger the fluorescence intensity of diamonds, the lower their value. However, for diamonds with colors below J grade, fluorescence has little effect and instead makes the diamond appear whiter. However, for diamonds with higher color grades, fluorescence will make them appear bluer overall and less transparent.
Diamond fluorescence level
According to international standards, diamond fluorescence is divided into 5 levels, and the diamond fluorescence level classification table from high to low is: None, Faint, Medium, Strong, Very Strong.
No fluorescence: Diamonds do not react under ultraviolet radiation.
Faint weak fluorescence: Diamonds can see weak fluorescence under ultraviolet radiation, but cannot distinguish color.
Medium fluorescence, Strong strong fluorescence, Very Strong very strong fluorescence: Under ultraviolet irradiation, diamonds have obvious visible fluorescence and colors can be distinguished (such as blue fluorescence, yellow fluorescence, etc.).
The Effect of Fluorescence on Diamonds
The impact of diamond fluorescence on diamonds is divided into "positive effects"
and
Negative impact.
