Rough diamonds and how we make them cut diamonds or loose diamonds

Diamonds are infamous for their brilliance, especially when they are cut well. Other important aspects to determine its value will involve the clarity, color and carat. In some cases, you will find a rough diamond that is set into a piece of jewelry. These are uncut and unpolished diamonds that are used in their original state.

The Design

DiamondsThere are some jewelers who create designs using rough diamonds and there are others who mix the rough diamond with polished diamonds for a rustic look. Raw or rough diamond is sometimes cut to produce loose diamonds. They are then carved and shaped carefully into decorated jewelry. At this stage, the product can have a higher market value that will be determined by an appraiser.

The Initial Steps

When converting rough diamond to cut diamond, there are several steps to follow. In the first phase, the rough diamonds are organized into various sizes and shapes. During the sorting of shapes, it doesn’t matter whether the diamond is brilliantly round or princess cut, but rather that it is easy to make and can be sawed.

Diamonds that have a shape which can produce one large cut are considered makeable. If the diamond is able to be cut in half to make two smaller diamonds, it is considered sawable.

Each of the rough diamonds is computer scanned with a Sarin machine. Computer software is used to scrutinize the various cutting alternatives. This stage is very crucial to the finished product because it evaluates the ultimate beauty of the diamonds.

Polishing

To preserve a greater proportion of the initial carat weight, the diamond could be made a little deeper and taller. You will find that in this case, the diamond’s weight will be more, but may not replicate the light that well, which means that they won’t have that much sparkle. Once the choice of cutting has been established, the diamond will be given to the polisher.

The polisher will place them into the first eight facets. Four will be placed in the pavilion and the other four placed in the crown on top of the stone. A special bracket is used to secure the diamond; holding it at a specific angle. It is then let down onto a turntable enclosed in a diamond paste that gradually polishes material away from the rough diamond.

The Next Stage

In this phase, the diamond is made in a rounded shape with a bruting machine. To transform the diamond into a rounded shape, two diamonds are positioned away from each other. The diamond’s girdle will then have a matte finish. With the diamond being shaped, it is then taken to another polishing phase where the crown and pavilion facets are polished so that both can match the original cutting strategy.

Conclusion

Each individual facet is carefully examined after polishing has been completed. This is orchestrated by the use of a laser scanner and afterwards by a professional. This is the phase where the grade will be assessed and established.
