–°ut and Polished Diamond vs Rough

In the diamond industry, yield refers to the proportion of rough diamond weight that is converted into a finished, cut and polished diamond. The yield of a rough diamond is an important factor in determining the profitability of the diamond cutting and polishing process. This article will explore the differences between cut and polished diamonds and rough diamonds and the significance of yield in the diamond industry.

Rough Diamonds

Rough diamonds are diamonds that have been extracted from the earth and have not yet been cut or polished. They are usually triangular or octahedral in shape and can range in size from a few millimeters to several carats. Rough diamonds are sold by weight and can be sold as individual stones or as parcels of multiple stones.

Cut and Polished Diamonds

Cut and polished diamonds are diamonds that have been cut and polished from rough diamonds. The cutting process involves the removal of excess weight from the rough diamond to create a diamond with optimal proportions, symmetry, and finish. The polishing process involves the smoothing of the diamond's surface to create a polished, shiny appearance.

Yield

The yield of a rough diamond refers to the proportion of rough diamond weight that is converted into a finished, cut and polished diamond. The yield of a rough diamond is determined by the rough diamond's shape, size, and quality, as well as the desired specifications of the finished diamond. The yield can range from as low as 5% to as high as 60%, depending on the rough diamond and the cutting and polishing process.

Factors affecting yield

There are several factors that can affect the yield of a rough diamond, including the shape and size of the rough diamond, the quality of the rough diamond, and the desired specifications of the finished diamond. Some rough diamonds may have inclusions or other imperfections that must be removed during the cutting process, reducing the yield. Additionally, the cutting and polishing process can be more complex for certain shapes and sizes of rough diamonds, reducing the yield.

Significance of yield

The yield of a rough diamond is an important factor in determining the profitability of the diamond cutting and polishing process. A higher yield means that more rough diamond weight is converted into finished, cut and polished diamonds, resulting in higher profits for the diamond cutting and polishing industry. On the other hand, a lower yield means that more rough diamond weight is lost during the cutting and polishing process, resulting in lower profits.

So wield refers to the proportion of rough diamond weight that is converted into a finished, cut and polished diamond. The yield of a rough diamond is determined by several factors, including the shape and size of the rough diamond, the quality of the rough diamond, and the desired specifications of the finished diamond. The yield is an important factor in determining the profitability of the diamond cutting and polishing process and is an essential consideration for anyone involved in the diamond industry.
