(Answer #1). The critical angle is the largest angle at which light rays inside a diamond can escape. The more a material bends light, the higher the RI Refractive index, the smaller its critical angle.Because diamond has a high RI, it has only a small critical angle, 24.5 degrees.Answer #1). The critical angle is the largest angle at which light rays inside a diamond can escape. The more a material bends light, the higher the RI Refractive index, the smaller its critical angle.
What is diamond fluorescence? Diamond fluorescence, in its most simple form, is the effect that ultraviolet (UV) light has on a diamond. When you stand under a blue light or ultraviolet light, sometimes you can see your whites get brighter or your teeth appear to glow. This is the same effect the diamond has under the UV rays. Fluorescence is the visible light that a diamond emits when it is exposed to the UV rays. On a GIA Diamond Grading Report, fluorescence refers to the strength, or intensity, of the diamondâs reaction to long-wave UV, which is an essential component of daylight.
