Diamond Cut Shapes
Diamond Shape Guide

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.

Round

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.

Princess

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%.

Emerald

Unlike the round brilliant cuts where the little sparkles of light bounces off, the step cut facets of emerald cut diamonds seem to flash ‘on’ and ‘off’. The scintillating patterns of the cut are different from the typical round cuts. In emerald cut diamonds, the dimension of the table varies from 61% to 68% and depth from 60% to 65%.

Pear

In the most basic feature of pear cut diamonds, with the apex of the rounded arc, a point needs to be lined up. Moreover, the two sides of the rounded arc must be symmetrical. 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%.

Marquise

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%.

Cushion

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. There will also be an added brilliance in this kind of cutting that appears something like that of a round modern diamond. The table percentage of an ideal cushion cut is from 56% to 63% and a depth of 58% to 66%.

Oval

Albeit the oval shapes can be thinner or broader, the most perfect oval cut diamonds come in the ratio of about 1.3 to 1.4. However, a bow tie effect can be found in oval cut diamonds especially in highly deep or shallow stones. An ideal table percentage measures from 54% to 58% and a depth of 62% to 66%.
