Diamond Cut

DIAMOND CUT

Cut is the only one of the 4Cs that is influenced by the human hand. The rest (color, clarity, carat) are created naturally as diamonds form in the earth.

Diamond Cut

Diamond cut refers to the angles and proportions a skilled craftsman creates in transforming a rough diamond into a polished diamond. Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and ultimately, value.

Cut also refers to the shape of a diamond - round, emerald or princess for example. A round diamond is symmetrical and therefore capable of reflecting nearly all the light that enters, thus labeling it the most brilliant of all diamond shapes. Non-round shapes, also known as "fancy shapes", follow different proportion guidelines to be considered well-cut. Generally speaking there are seven principal diamond shapes: Round, Marquise, Emerald, Princess, Pear, Oval and Heart. Side-stone options include Baguette and Trillion cutting styles. Diamond cuts and cutting styles work in harmony to create a diamond's brilliance.
