Many people confuse cut with the shape (e.g. round or princess) of a diamond. The shape of the diamond is a matter of personal preference and does not directly affect the value. Cut refers to how well the stone is faceted, proportioned, and polished. A good cut will result in a better brilliance, which is why it is the most important of the 4Cs. If a diamond is poorly cut, the diamond will look dull and glassy. It is the work of a master cutter that allows the diamond to be cut in such a way as to permit the maximum amount of light to be reflected through the diamond. The cut is the only diamond component not influenced by nature.

What is the best diamond to buy?
In diamonds under 1 carat, clarity should be considered the least important of the 4Cs. Brilliant-cut diamonds (such as round, princess, cushion, oval, pear, and marquise) hide inclusions better than step cuts (emerald and asscher).
The 4Cs stand for colour, clarity, carat weight, and cut. They make up a grading system that determines the quality and price of a diamond.
