We will delve more specifically on one part of this journey, the 5 steps of the cutting process and what makes a rough diamond the sparkly polished stone people look forward to setting it in their engagement ring.

Cutting diamonds is a very specific art that is usually transmitted from one generation to the other, either in the same family or through a Master and his apprentice. It takes a lifetime to master and is quite different to any other lapidary work.
- Planning. Planning is a crucial step as it is the planning time that will define the final result. Planning involves: maximising the value of the diamond by choosing the right marketable shape that will sell most. Secondly, studying the weight retention in order to get the most out of your rough, as on average, there is a 50% weight loss when cutting a diamond and it is a sector that works on a per carat value. Thirdly, cutting can influence the colour grading, therefore certain cut shapes have to be used to intensify a colour.
- Cleaving or sawing. This is the part where the diamond rough is split into separate pieces by either using a laser or a mechanical saw.
- Bruting. Once the rough has been split, the bruting process is used to create a round shape. Both diamonds are placed on a spinning axle across each other. And since they rotate very quickly in opposite directions, they grind each other and make a rough girdle finish.
- Polishing. Once the stones are round, then starts the process of cutting the smooth facets onto the diamond using a spinning wheel. This procedure actually includes two further steps, the blocking and brilliantering. The blocking is setting the base of the single cut by adding the table, 16 facets and the culet. The brillianteering phase finishes the polishing by adding the remaining facets taking the stone to a total of 58 facets.
- Inspection. This is the last stage of the process. It is very important that the diamond meets the quality control standards as specified by the manufacturer otherwise the diamond is sent back to the polishers.
You will now look at diamonds even more fondly, knowing all the steps it takes to make the stone look perfect for your engagement ring.
