Over time, diamond-cutting techniques evolved, and new tools were developed to improve the process. In the 17th century, the rose cut was introduced, which featured a flat base and a dome-shaped top with triangular facets. In the 19th century, the brilliant-cut was introduced, with a circular girdle and a cone-shaped bottom with triangular facets.

Today, diamond cutting is a complex and sophisticated process that involves cutting and polishing the diamond to precise proportions and angles to maximize its brilliance and fire. The process requires specialized tools and techniques that have been developed over centuries of diamond cutting history.

The Diamond Cutting Process :

The diamond-cutting process is a multi-stage process that involves cutting and polishing a rough diamond into a finished gemstone. The process requires skill, precision, and specialized tools and techniques.

The diamond-cutting process typically involves the following stages:

Planning – The first stage of diamond cutting involves planning the cut. This is done by examining the rough diamond to determine the best cut to maximize its beauty and value.

Cleaving: Once the diamond is planned, the next stage is to cleave or cut it into smaller pieces along its natural planes. This is typically done using a particular diamond saw.

Bruting: After cleaving the diamond, the next stage is to shape the diamond. This is done using a process called bruting, which involves shaping the diamond into a cone-shaped form.

Faceting: The next stage is to cut the facets of the diamond. This is done using specialized diamond cutting tools that allow precision cutting of the diamond’s angles and proportions.

Polishing: The final stage is to polish the diamond to enhance its shine and brilliance. This is done using a series of polishing wheels that gradually smooth the diamond’s surface until it is perfectly polished.

Precision is of utmost importance in the diamond-cutting process. To maximize its beauty and value, the diamond must be cut and polished to precise proportions and angles. A minor error in cutting or polishing can significantly reduce the diamond’s value. Therefore, diamond cutters must have exceptional skill and attention to detail to ensure that each diamond is perfectly cut and polished.

In summary, the diamond-cutting process is a complex and multi-stage process that requires skill, precision, and specialized tools and techniques.
