(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.
Some as Slight fluorescence or Very Slight fluorescence. The concern of the costumers, buy diamonds that are fluorescence will show a milky light even under regular light environment. Some dealers or jewelers will try to sell the fluorescence or the presence of the fluorescence a s â a Good think â but the truth is that will never be the truth . Fluorescence make the diamond cheaper and in all markets, all over the globe, a NONE FLUORESCENCE grade in a diamond is much more appreciated than any fluorescence grade.
