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
