Table: The flat face on the top of the diamond.
Girdle: The outer edge of the diamond that separates the top half of the diamond (the crown) from the bottom half (the pavilion).
Symmetry: Refers to the balance of the diamond. Diamonds that are cut evenly according to the geometeric patterns that define their shape have good symmetry.
Finish: Refers to the quality of exterior surfaces of the diamond. The fewer blemishes a diamond has, and the smoother the surfaces of the diamond are, the better the finish is.
