Refractive Index shows the comparison of light speeds in two mediums. Light may travel from rarer to denser medium or from denser to rarer medium. When we say refractive index of diamond is 2.42, it means light is travelling from rarer to denser medium, and speed of light in air (vacuum) is 2.42 times the speed of light in diamond. On the other hand if the light travels from denser to rarer medium, that is, from diamond to air the refractive index will be 1/2.42.
