the complete reflection of a light ray reaching an interface with a less dense medium when the angle of incidence exceeds the critical angle.

Sharper diamonds reflecting lot of light is due to internal reflection.

Total internal reflection is a phenomenon which occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface

When light travelling in a denser medium is incident at the surface of a rarer medium such that the angle of incidence is greater than the critical angle,(for d given pair of media) the ray is totally reflected back into the denser medium.this phenomenon is called total internal reflection.
