Refractive index of crystal

- Aug 19, 2019-

Refractive index (RI) : 1.544-1.553, hardly beyond this range.(the refractive index is the ratio of the incident Angle sine to the refraction Angle sine when the light penetrates through the gem crystal through air and causes the refraction phenomenon.)
