What is a diamond dealer?

Coming from a training as a gemologist or lapidary diamond option, he is the guardian of all the traditional techniques that have endured for centuries in the art of shaping diamonds. He cuts, cleaves, cuts and polishes the stone to reveal to the world all the magic of the diamond in its most perfect and accomplished form. Diamond cutting is an art that has been practiced since the 15th century. And the same gestures are still reproduced today.

What are the actions of the craftsman?



Before using his tools, the diamond cutter must imperatively define the size by means of a careful examination of the shapes and contours of the diamond still raw. Because it is the natural form of the stone which is decisive for its future use. The stone is marked with felt before being cut or sawn.

Cleavage or sawing

Cleavage consists of separating the stone into two or more pieces suitable for size, using an iron or steel blade. The craftsman must show extreme precision in his gesture so as not to slice but to separate without breaking. Diamond being the most solid stone in the world, the craftsman must cleave at the weakest point of the stone. With the patience of an alchemist, the cleaver must succeed in separating matter. This is the first approach to get the best of rough diamond, in its future most exploitable form (tetrahedron). Sawing is often preferable to cleavage, especially when the stone has no point of weakness.

Bruting or size

This crucial phase allows the final shaping of the diamond. The stone is scrupulously examined by the detacher to determine the places where it can be rounded, shaped in the respect of proportions. The craftsman uses another diamond to cut his stone and various machines of very high precision.

Faceting or polishing

This is the last step for the diamond to be a fair and perfect cut stone. However, various actions such as the setting in eight, the brilliance and the polishing, are essential to finally reveal the degrees of brilliance and the firepower of the diamond.

A diamond expert to evaluate its quality

If the gesture of the diamond cutter must be precise, meticulous and perfectly organized, its visual acuity is just as much involved. It is he who has the expertise and the knowledge to evaluate and give a price to the diamond, in order to be sold, at the best price, to the jewelers. Its quality is examined according to precise criteria: the 4 Cs (carat, size, purity and color). This selectivity crowns this expert in his art of precision.
But to be of better advice and to establish his fame, the diamond dealer must also be able to evaluate the emotion and the life present in this stone of exception. The refractive index of the light, the brightness, the history of its size are the vibrations of the soul of the diamond skilfully cut. Ready to be enshrined in pure gold, only the craftsman is depository of his birth and he alone will offer him his most beautiful cradle. For eternity.
