The first objective is that of maximum return on investment for the piece of diamond rough. The second is how quickly the finished diamond can be sold. Scanning devices are used to get a 3-dimensional computer model of the rough stone. Also, inclusions are photographed and placed on the 3D model, which is then used to find an optimal way to cut the stone.

Maximizing value[ edit ] Man-powered diamond cutting mill in 18th century The Diamond polishing of maximizing the value of finished diamonds, from a rough diamond into a polished gemstone, is both an art and a science.

The choice of cut is influenced by many factors. Market factors include the exponential increase in value of diamonds as weight increases, referred to as weight retention, and the popularity of certain shapes amongst consumers. Physical factors include the original shape of the rough stone, and location of the inclusions and flaws to be eliminated.

Weight retention[ edit ] The weight retention analysis studies the diamond rough to find the best combination of finished stones as it relates to per carat value. For instance, a 2.

Since the per-carat price of a diamond shifts around key milestones such as 1. Color retention[ edit ] The carat Oppenheimer Diamond —an uncut diamond does not show its prized optical properties.

In colored diamonds, cutting can influence the color grade of the diamond, thereby raising its value. Certain cut shapes are used to intensify the color of the diamond. The radiant cut is an example of this type of cut. Natural green color diamonds most often have merely a surface coloration caused by natural irradiation, which does not extend through the stone.

It is these naturals that provide the color to the diamond. Turnaround minimization[ edit ] The other consideration of diamond planning is how quickly a diamond will sell. This consideration is often unique to the type of manufacturer.

While a certain cutting plan may yield a better value, a different plan may yield diamonds that will sell sooner, providing an earlier return on the investment.
