Each of the diamond cut shapes stones are molded out in certain proportions where the depth and tables are considered to a great extent. Moreover, the cut grade is yet another factor that defines the overall visual appearance of a diamond. Through the crown and table facets, an ideal cut diamond will reflect almost 100% of the light that enters. Following are some specifications that promise maximum brilliance.
The maximum amount of light dispersion and brilliance is acquired in the round shape of a diamond with its 57 facets. Most suitable proportions of round diamonds of an ideal cut are almost 54% to 57% in the table and 60% to 63% in its depth.
While selecting the stones to the mold princess cut, try not to pick stones with a lesser table percentage than its depth percentage. A perfect square would be the most appropriate ratio to be carved into the princess cut. For the same, the table must be 63% to 70% and a depth of 67% to 76%.

A pertinent pear cut can be carved out from stones that are of 1.4:1.6 in length to width ratio. When deciding the table percentage of the stone, it is almost 57 to 62%. Meanwhile, the depth is in between 58% and 64%.
Although it depends on personal preference, the most appropriate marquise diamond can be found in a specific length to width ratio. A marquise diamond will look stunning in the ratio of 1.7 to 2.0. The most preferred table percentage is of 55% to 63% and when it comes to depth, it is nearly 58% to 64%.
The modern cushion cuts have way much smaller facets rather than the larger and broader facets of the older counterparts. Furthermore, the newer cuts have a number of facets.
