Diamond Cut

Many people confuse the cut as simply being the shape of a diamond and while the shape is part of the cutting process, it is just the beginning. A diamond's cut is not only about its shape, but how effectively the stone can return light back to the viewer's eye. A well-cut diamond will appear very brilliant and fiery, while more poorly cut stones can appear dark and lifeless, regardless of their color or clarity grades. The cut can be defined as the proportions of the diamond including all the facets and their placement in respect to one another.

There are many factors that affect the light performance of a diamond; however the stone's proportions are the largest factor in creating the roadway for the light to travel. The proportions of a diamond are measurements that include the depth or height, length and width, the table size and pavilion height. Not only do well-cut diamonds appear more brilliant, they can also appear larger than other stones of the same carat weight. An ideal stone has both increased brilliance as well as increased diameter relative to more deeply cut diamonds.


Too Shallow

Too Deep


Light is properly directed through the table and the diamond will have optimal size and brilliance.

Too Shallow

Light will escape out the bottom and diamond will look dark from the top.

Too Deep

Light will escape out the sides of the diamond and it will look dull. It also makes the diamond look smaller

In some cases the color and clarity grade of a diamond can have less effect on the diamond's brilliance and fire than the cut. Genesisdiamonds.Net carries the finest cut diamonds chosen specifically for their brilliance, regardless of color or clarity.
