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.

The first step for dimaonds wholesale is to carry out sieving to separate the diamonds based on size. The lot is sub divided and the weights are reconciled.

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.
