Manufacturing of diamonds is a very complex and time-consuming process. It requires a lot of human skills and modern machinery. Each and every diamond is planned separately and goes in couple of hands to decide best yield and plan. In diamond manufacturing, a lot of importance is given to planning. Once the diamond is planned and its yield estimated, everyone in the production line tries their best to achieve the set target. Diamond is analyzed during and after each process.

Diamond manufacturing process:

  • Rough Diamond Analysis and Assortment
  • Rough Diamond Planning and Marking
  • Cleaving and Sawing
  • Bruting
  • Polishing and Grading

Rough Diamond Analysis and Assortment

Rough Analysis with OGI Machine

This is the initial stage of diamond manufacturing process. In this process expert checkers analyzes the rough diamond and its characteristics are determined. These characteristics are based on color, clarity, carat, cut. After deciding 4 Cís, it is given a grade, which represents overall quality of the rough diamond.

Rough Diamond Planning & Marking

Diamond Marking with Sarin Marker

After the rough diamondís grade is decided, the experienced marker takes decision on how the rough diamond should look when it is converted into polished diamond. The planner makes estimate of what is going to be its weight and cut. Planner marks the diamond with a special pen. Planning a rough diamond means calculated forecasting. Once the diamond is planned and confirmed, the rest of the production line follows. Its planned in a way that the estimated target can be achieved.

Cleaving and Sawing

Cleaving and sawing are the two different processes that come after the rough diamond is planned and marked. The rough is analyzed and sent to either cleaving or sawing department. A rough diamond needs to be broken into parts. That can be done through either of the method.

Cleaving is done manually with hammer, which split rough diamond into two or more parts. If the diamond needs sawing, then it is sent to sawing department. Laser technology is the latest and most advanced technology for sawing. Laser technology gives very accurate result. Planner rechecks the diamond after this process is complete.

Bruting

Bruting at Jeely

The next step in the diamond processing is giving shape to the stone. This gives shape to diamond in a way so that maximum yield can be taken. The bruter has to take care of many things. He should keep in mind the yield after Bruting and also that the diamond doesnít break.

Various advanced machineries are used in the Bruting process.

Polishing

Polishing is the final step in the diamond manufacturing process. Here the diamond is given the final look. The polisher is very careful at this process because a small mistake can result into quality loss of the diamond. Polished diamond is sent to grading department for the final decision on quality. Here the 4 Cís of diamonds are decided and given grade according to international quality standards.

Infrastructure for manufacturing

We have deployed most advanced machineries and tools for diamond manufacturing. We have talented and knowledgeable people at our premises. We have imported machineries for all the processes from reputed companies like Sarin, OGI etc.
