Cut refers to the angles and proportions a skilled craftsman creates in transforming a rough diamond into polished diamonds. Nature determines so much about a diamond, but it takes a master cutter to reveal the stone’s true brilliance, fire and ultimate beauty. Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another, and disperse/reflect light 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 throught the side or bottom, resulting in less brilliance and ultimately, value.
Cutting style is categorized into three basic types: Step -cut, brilliant -cut, and mixed-cut. The difference among theses three types is the faceting arrangement of each style.
How a diamond handles light:
It is the cut that enables a diamond to make the best use of light.
- When a diamond is cut to good proportions, light is reflected from one facet to another and then dispersed through the top of the stone.
- If the cut of the diamond is too deep, some light escapes through the opposite side of the pavilion.
- If the cut is too shallow, light escapes through the pavilion before it can be reflected.

Cut also refers to the shape of a diamond- round, marquise, pear, or heart shaped. Since a rounds diamond is symmetrical and capable of reflecting nearly all the enters, it is the most brilliant of all diamond shapes. Cut and cutting style work in harmony to create a Diamond’s brilliance.
