A diamond is a crystalline mineral made up of carbon. The building blocks of crystalline materials, molecules and atoms, are arranged on a certain geometrical manner. Most of the diamonds are not colorless. There are large variations in color tone and color saturation. Diamonds have an exceptional hardness and therefore the processing of diamonds is very complicated and difficult.

A diamond may contain inclusions or structural changes. They have evolved during the formation of the diamond in the depths of the earth. They appear as black or white spots.

A diamond may also contain a glets or a feathers caused by the collision with rocks during the formation. They resemble cracks in broken glass.

Before a diamond is manipulated, it needs to be very well analyzed and studied. The consultant has a thorough knowledge of the crystallization of the diamond and its irregularities. He must be able to tell from outside the stone how an inclusion can be removed. The following three rules always have to be respected:

Obtaining stones in good proportions to polish. Retaining a maximum of weight by removing a minimum of material. Obtaining as many usable pieces as possible.

With ink the direction in which the diamond must be cleaved and/or sawn, will be indicated. This is what we call the marking of a diamond.

Due to his know-how the professional will also be able to make an excellent judgment about the value of a polished stone.
