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
- Polishing and Grading
Rough Diamond Analysis and Assortment
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
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.
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 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.
