Measurements Of A Diamond

Table

The table is the largest facet of the diamond. One of the key factors to determining a diamond’s grade of cut is the ratio of the table diameter to the diameter of the diamond.

Depth

Depth is the measurement of the diamond from the culet through the center of the diamond to the table.

Culet

The culet is the point at the bottom of the diamond.

PAVILION

In a Round Brilliant, the cone-shaped lower part of the stone

PAVILION ANGLE

If the pavilion is too deep light will not escape. If the pavilion is too shallow, light will not reflect and the diamond will appear glassy.

GIRDLE

This is the edge of the diamond typically held by the setting.

CROWN ANGLE

If it’s cut for brilliance, the most sparkle will be reflected. The crown angle in the well-cut diamond should be 33 to 35 degrees

CROWN

The crown happens to be the biggest facet on the diamond

Learn the measurements of a diamond to determine how much sparkle a diamond can produce.
A diamond’s shape as well as its polish and symmetry affect the behavior of the stone; this effects how light reflects.
