It causes light to slow down significantly.
The base line for the index of refraction is the amount of directional deviation that is produced when a beam of light travels from the air into another substance. The term "high index" is a relative term. Glycerin actually has a low index of refraction when compared to motor oil. I can't be certain but I believe that the density and opacity of a substance plays a big part in the determination of it's relative index.
The (very high) refractive index of diamond is 2.4 at room temperature.(From Wikipedia: "Refractive index also describes the quantity that light is bent as it passes through a single substance."
Atomic refraction is very high.
due to the process of refraction of light refraction is a process of bending of light when moving from one medium to other our eyes can view any object when the reflected light reaches the the human eye only thus similarly for any object the the reflected light is needed to see it but in this case where a certain amount of refracted rays some reflects back to our eyes.this gives the image of the coin but when the refraction is so high such that the reflected rays never reach our eyes and the coin disappear . note:do not confuse between the reflection and refraction
A transparent medium is sometimes said to have a high optical density (or to be relatively dense) if it has a high refractive index.
Silicon, with an index of 3.96, is the lowest I could find.

The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
The ray is diffracted so that its path moves closer to the normal at the point of incidence.

If a beam of light enters a substance with a higher density than air and at an angle, the light is refracted so that an object on the far side of the substance appears to be closer to the observer. If the density of the substance is lower than that of air, the light is refracted away from the observer and the object being viewed appears to be farther away.
Not necessarily. Diamond molecules are comparable in mass to those of water, yet diamond has a far higher index of refraction over water.
Atomic refraction is very high.
The high index of refraction of diamond produces a rainbow effect of multi-colored glitter. This is difficult to reproduce in the less expensive materials used for costume jewelry.
