Polishing Of Rough Diamonds

The polishing of the diamond begins; one by one, facets will be ground on to the stone. A facet is the tiny plane or surface that traps the light and makes a Diamond sparkle. Most diamond cuts have 58 facets.

The facets are applied to the Diamond on a "turntable", made of porous iron, which has been coated with diamond dust and oil. The diamond is set into a holder and held against the turntable as it revolves at a very high speed.

A diamond has been cut well when its facets are clean, sharp, and symmetrical, and the proportions above and below the girdle are correct. A diamond is correctly proportioned when one-third of the total weight of the gem is above the girdle and two thirds below. A well-cut diamond will be fiery, brilliant and beautiful.


This process involves diamond professionals marking the diamond, to explain how it is going to be cut or shaped after which the diamond is sent to the shaping division. Indian diamonds wholesale industry has highly skilled professionals for marking.

Laser Sawing and Cleaving

Once the diamonds have been sent to the Shaping division, they are sent for Sawing and Cleaving.

Cleavable goods are marked for Laser Sawing and Sawable goods are marked either for Blade Sawing or Laser sawing. Goods are also marked for making “window” to facilitate checking of internals of the diamonds. Shaping is given a great deal of importance as it is crucial to efficient diamonds wholesale.


Bruting is the process of giving shape to the rough diamond. A person doing this has to take care of many things as the rough diamonds is of 'vivid' shapes and resembles a normal stone. The butter has to take its utmost care of the diamonds at this process so that it does not break.

Also in this process the butter has to leave as much of natural skin on the piece of diamond as possible. This is because one can check out that the weight loss of the diamond in this process is not more than required. The minimum natural left has to be in a particular way, i.e. it has to be on the table as well as the bottom of diamond. At bottom of the diamond it has to be in three position so as to cover the circumference of the diamond. In the whole process of bruiting the main aim of the Bruter is to give a shape to the rough diamond in such a way that its optimum effect can be achieved by polisher, without any extra weight loss than required.

Cutting and Polishing

After being bruted a diamond passes to the polishing department where the final work of faceting is done. Polishing means the process of giving the diamond its final look. Each diamond has to be cut according to its requirement, and polished to bring out its shine. It is in this process where in the rough diamonds are made perfect. In diamonds wholesale, a great variety of cuts are available and each has its own charm and significance.

This is last step in manufacturing process of diamonds, from here diamonds passes to the Grading department.
