Diamonds before Cutting

It is obvious that diamonds don’t come from the ground looking like at the store. Before cutting the diamond has jagged edges, and it is a very rough milky stone. The cutter’s job is to make it into something beautiful. There are five steps every cutter follows. The first thing is the planning which is very important because they must analyze the rock and figure out a way to minimize waste. The goal is not to drop the value of the rock.

Cleaving and Sawing

The diamond is the weakest along the tetrahedral plane, and the cutter must cleave there before cutting. A cement or was mold is holding the diamond in place as the worker carves sharp incision along the plane. They cut it into two pieces by placing a steel blade in the incision and striking it. You have to use some force to do this, it won’t make any damage to it.

It can happen that cleaving isn’t enough because there is no weak point, so you have to use other methods. Sawing is the second method they use, and this is done with a phosphor-bronze blade that rotates at about 15k rpm. There is advanced technology now where lasers are used to do the cutting, but it takes much longer to finish the process. At this step, the cutter needs to decide with part will be the flat top of the diamond, and which will be the outside rim also called girdle.

Cutting or Bruiting

The most important part besides planning is making the correct shape. These techniques are the same thing, but the bruiting is done by hand and cutting is done by the machine. An interesting thing is that diamonds are used to cut diamonds if the cutter shapes them by hand. They rely on their hardness. The instrument used looks like a stick with a tip that carries the diamond.

Only one corner is exposed at the top of the stick, so it will be sharp. They use two sticks in the process, one for the diamond being processed. By rubbing the parts, they make the desired shape. In most cases, they will use the mechanical process where they place it in a lathe and rub it against another diamond to make the rough finish. Click here to read more.
