‘Pre Marking Stage.’
This refers to the process of separating
the goods “makeables” (ready for manufacturing) and others which require processing.
Goods other than makeables are taken up for marking. In diamonds wholesale industry, this concept does not require any explaination as it is very basic.

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.

and Cleaving. Cleavable goods are marked for Laser Kerfing. Sawable goods are marked
either for Blade Sawing or Laser sawing. Goods are also marked for making “window”

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.

Once the diamond has been cut and polished to perfection for diamonds wholesale, it is sent to the Assortment
division, where the diamond is assorted according to its cut, carat, colour and
clarity.
Each assorted packet is given the following identification:
- Cut Number
- Weight in Carats
- Sieve size where applicable
- Purity

After the diamonds have been assorted they are sent to the quality check division,
where they are checked by professionals. Once the diamonds have passed the quality
check, they are graded accordingly. Although diamonds wholesale involved processing in
large quantities, we make sure that each diamond is thoroughly tested and approved for quality.

After quality check, diamonds go to the grading department. The already faceted
diamonds are inspected and fine polished if necessary and then boiled in hydrochloric
and sulphuric acids to remove dust, oil and other grit that might mar its shine.

kapan wise. This is done by some of the most experienced professionals in the diamonds wholesale industry.
