Our Diamond Cutting and Polishing Course are held in Ramsgate, and Cape Town South Africa.
The basic diamond-cutting process includes these steps; planning, cleaving or sawing, bruting, polishing, and final inspection. A simplified round brilliant cut process includes the following stages:
Planning – Modern-day planning of a diamond is done using computer software.
Marking – Outlining the best possible shape and cut of the diamond.
Sawing the rough stone – depending on the shape of the rough diamond as not all diamonds are sawn.
Table
Bruting the girdle.
Blocking 8 main pavilion facets – these facets are divided into 4 corners and 4 pavilions as the corners and pavilions run in different directions due to the atomic structure of the diamond.
Crown – the crown consists of 8 main facets and is divided into 4 corners and 4 Bezels.
Final bruting – ensuring the diamond’s girdle is perfectly round and smooth.
Polishing all 16 main facets.
Brillianteering – Adding and polishing 8 stars and 16 pavilion and 16 crown halves.
Quality control – checking for symmetry, polishing, and cutting (angles) after the diamond is completed.
This is just one, although a fairly common way of creating a round brilliant cut. The actual process also includes many more stages depending on the size and quality of the rough stone. For example, bigger stones are first scanned to get the three-dimensional shape, which is then used to find optimal usage. The scanning may be repeated after each stage and bruting may be done in several steps, each bringing the girdle closer to the final shape.
It is possible only because the hardness of a diamond varies widely according to the direction in which one is trying to cut or grind.
