Why are diamonds are excellent with total internal reflection?
Refractive index of the medium is equated to 1/ sin C Here C is the critical angle. Diamond has high refractive index more than 2. So critical angle becomes very low. So for falling radiations at angles of incidence greater than this smaller value of critical angle, total internal reflection becomes possible.
