ANATOMY OF A DIAMOND AND THE EFFECTS OF LIGHT

DIAMOND CROWN

The crown is the top part of the diamond, between the table and the girdle.

DIAMOND CULET

This is the bottom tip of the diamond, which is usually never on show.

DIAMOND DEPTH

The height of the diamond.

DIAMOND DIAMETER

The width of the diamond.

DIAMOND GIRDLE

This is the narrow band at the diamond’s narrow point.

DIAMOND PAVILION

The bottom part of the diamond, between the cutlet and the girdle.

DIAMOND TABLE

The largest facet at the top of the diamond.

The two main parts of the diamond that need to be considered are the pavilion and the crown. Their relationship with one another is what determines how well the diamond sparkles.

So, what happens when the light hits a diamond that has been cut well? Well, some of the light will immediately reflect back off the crown angles while the rest of the light will enter the diamond. When it enters the diamond, it should bounce off the internal walls and then shoot back to the surface of the diamond again, creating a stunning sparkle. If the diamond has not been cut well, the light will escape.
