The cut of the stone determines its brilliance. Only a perfectly proportioned cut gives the diamond its optimum brilliance. In order to always offer stones respecting this criterion of excellence, Maison FRED makes a strict selection of its diamonds.

The purity of a diamond is defined by the number, type, size and position of inclusions present in the stone. Like any natural stone, almost all diamonds contain inclusions. A diamond is considered to be ”flawless” if there are no inclusions if it contains no visible flaws when magnified 10 times. Maison FRED only selects stones with a degree of purity between IF and VS2, which is the guarantee of an exceptional clarity and a lack of inclusions visible to the naked eye.

The whiter a diamond is, the rarer and more precious it is. The colors of FRED diamonds are exclusively between D and G.

The unit of measurement for diamonds is the carat. One carat corresponds to 0.2 grams. The weight of the diamond combined with its size, colour and clarity determines its value.
