Table Percentage
Table Percentage is an important measurement used in diamond cutting that refers to the size of the flat area on top of a diamond (called the table) compared to the diamond's total width. Think of it like measuring how much of a pizza is taken up by its center compared to the whole pizza. This measurement helps determine how well light moves through the diamond, which affects how sparkly it looks. Diamond cutters need to achieve the right table percentage to make sure the diamond looks its best and maintains its value. The ideal table percentage usually falls between 54% and 57% for round diamonds, though this can vary for different diamond shapes.
