Marking The Diamond

No engagement ring can look good without a beautifully cut stone, unless you specifically prefer a simple band with no gems on it. Most people want glam and sparkle to show off on their fingers, which makes a well-cut diamond or alternative gem indispensable. Diamond cutters work the hardest to ensure you have that option.

Few other professions require as much skill as diamond cutting. A professional cutter works under an established expert for years to pick up the minutiae surrounding cutting and polishing. There is no room for error once they start working on a stone, and their work basically comprises the following.

Following Instructions

A diamond assessor first evaluates the rough stone after it has been analyzed by a mapping machine. The diamond cutter follows the instructions the assessor provides, which include the layout and the specific style, cut, and shape of the intended result.

Marking the Diamond

After receiving the mapping results, the cutter sets to defining a cutting and polishing plan. After this, a craftsman marks the diamond using ink to designate the lines to cut along. The cutter then polishes the stone with a tang. Based on how big it is, the rough stone may need to be cleaved or sawed first.

Cleaving or Sawing

The rough diamond is either cleaved or sawed into two distinct pieces, keeping its various growth planes in mind. If the marking falls along a line, for instance, or parallel with the stone, cleaving is the way to go. For markings against the line, sawing is done using a laser, which is among the fastest and most accurate ways to cut a diamond.


After the diamond has been separated, a process called bruting or girdling is carried out. In this process, the diamond is set on top of a spinning axle, which spins the stones at high speeds, and in opposite directions. This gradually removes the rough parts, delivering a perfectly round stone.


To achieve a beautiful gemstone imbued with maximum brilliance, fire, and scintillation, it is vital to polish the bruted stone. This requires immense levels of precision and experience on the cutter’s part. The stone is placed on top of a rotating arm or tang, and then set against a spinning wheel or scaif. This polishes the rough stone into a gleaming gem.
