The princess cut is a square cut with sharp edges. It is the best choice among fancy cut diamonds for overall brilliance and fire. The princess cut utilizes most of the shape of the original rough diamond and the weight loss from cutting is low. It can therefore be more appealing in price than a comparative round cut of the same weight. Princess-cut diamonds can vary greatly in how square or rectangular they are. To find the dimension of the princess you want, see the length to width ratio below.
For princess shape to appear more square look for a length to width ratio to be equal or less than 1:1.10. If you like the look of rectangular shape took for length to width ratios greater than 1.10: 1.
