Stage 1: Planning to cut a rough diamond
The most complicated stage in the diamond cutting process is planning and analyzing the diamond rough, and it also demands the greatest skill and technology. During the design stages, the cutter will choose the best feasible diamond shapes in order to reduce waste and optimize the rough stone's output. To get precise measurements, the rough stone is often mapped with a Sarin machine. The marker, a highly experienced cutter who weighs all the factors and determines whether a diamond should be sawn or split into pieces, then marks exactly where the cuts should be made, performs these complex computations. This procedure might take months when dealing with huge, expensive gems.
Stage 2: Sawing or Cleaving diamond rough
The phase of the cleaving procedure that includes breaking the rough into distinct pieces is called cleaving. This will allow the cutter to work on the parts individually while also allowing the rough to be fully used. At this point, mechanical sawing is also an option. In the event of strangely shaped roughs, contactless cutting instruments like as lasers can be used to complete the sawing operation.
Stage 3: Creating the diamond shape
Following the creation and formation of the rough's rounded shape, the following step is to develop and form the diamond's facets. The rough is placed on a revolving arm, and the rough is polished using a spinning wheel. The diamond's facets are smooth and reflective as a result of this process. Following that, a procedure known as bruting or girdling is used to produce the shape of each gem's final outline. A computer-controlled bruting machine spins diamond against diamond to create a round diamond.
Stage 4: Inspecting the diamond (Quality Control)
The inspection stage is the final step. This is when the diamond is examined to ensure that it fulfills the manufacturer's requirements. If the stone didn't satisfy the quality control requirements, it would be sent back to the polishers for some touch-up work.
