The journey of a diamond, from the moment it’s mined, till it’s transformed into a rough diamond engagement ring is quite long. We’ll take a closer look at one part of this journey: the five steps for cutting the diamond and how long it takes to transform a rough diamond into the sparkly, polished stone people want in their engagement ring.

Cutting a diamond is a very specific art which is usually passed from one generation to the next, either in the same family or through a master and his apprentice. The process for creating an engagement ring takes a lifetime to master and requires unique skill.


  1. Planning. Planning is a crucial step as decisions made during this stage will determine the final result. A jeweller must plan how to maximise the value of the diamond by choosing the right shape. They must also study the weight retention to get the most out of your rough diamond engagement ring. On average, there’s a 50% weight loss when cutting a diamond and rings are valued per carat. Cutting can also influence the colour grading, so certain cut shapes can be used to intensify colour.

  2. Cleaving or sawing. During this stage, the rough diamond is split into separate pieces by either using a laser or a mechanical saw.

  3. Bruting. Once the rough has been split, the bruting process creates a round shape. Two diamonds are placed on a spinning axle across each other, which then rotates very quickly in opposite directions causing the diamonds to grind against each other and create a rough girdle finish.

  4. Polishing. Once the stones are round, the jeweller then cuts the smooth facets onto the diamond using a spinning wheel. This procedure actually includes two further steps, the blocking and brillianteering. The blocking involves setting the base of the single-cut by adding the table, 16 facets and culet. The brillianteering phase finishes the polishing by adding the remaining facets bringing the rough diamond engagement ring to a total of 58 facets.

  5. Inspection. Finally, the jeweller inspects the rough diamond engagement ring to ensure the diamond meets the quality control standards specified by the manufacturer; otherwise, the diamond is sent back to the polishers.

Now that you know more about the process behind creating your rough diamond engagement ring, you’ll look at your diamond even more fondly.
