Rough diamonds are diamonds that have not been cut, polished or have gone through any process or treatment after they have been mined. They are exactly are as they are after they have been found in the earth. Rough diamonds are also often referred to as uncut diamonds, raw diamonds or natural diamonds.
Rough Assortment
Job DescriptionIndividuals working as assorter have to separate polished diamonds and group them into lots having similar characteristics and reject which are not as per required quality. It is done by looking at the diamond through an eye glass under light and requires experience in spotting similar type of diamonds.
Diamond Planning
Detailed models of each diamond enable us to consider the possibilities of polishing the rough into one gem of maximum size or cutting it into several gems that are smaller in size, but offer greater quality and overall value.
CLEAVING OR SAWING
Once the planner decides where the diamond should be cut, the diamond is either manually cleaved or sawed. Sawing can be done with a diamond-coated rotary saw or a laser.
Bruting forms the basic face-up outline of a round diamond to prepare it for faceting. During the bruting phase the diamond being bruted is spun on a rotating lathe while another diamond is forced against it, gradually forming the rounded outline. Essentially, one diamond is used to shape the other.

Diamond Polishing
The final stage of a diamond's journey from the rough encompasses many steps, including blocking the pavilion and the crown into their basic shapes, and polishing the individual facets to the precise angles that will reflect cascades of light from deep inside.
