Method and device for processing a surface (5) of a diamond (1) with a mechanical part (3) which is moved in relation to the surface (5) of the diamond (1), whereby unbound diamond grains (2) are provided in between the mechanical part (3) and the surface (5) of the diamond (1), whereby the mechanical part (3) subjects the diamond grains (2) to a rolling motion over the surface (5) of the diamond (1), such that the diamond grains (2) move in relation to the mechanical part (3) and the surface (5) of the diamond (1), whereby the mechanical part (3) makes a mechanical contact with the surface (5) of the diamond (1) via the diamond grains (2), whereby this mechanical contact represents a contact length (8) over which the diamond grains (2) roll on the surface (5) of the diamond (1), mainly according to the direction of the relative motion of the mechanical part (3) in relation to the surface (5) of the diamond (1) and, whereby the diamond grains (2), with the support of the mechanical part (3), press themselves in the surface (5) of the diamond (1) while rolling, as a result of which microscopic fissures (6) are created in the latter surface (5) which then gradually crumbles off.

L'invention concerne un procédé et un dispositif de traitement d'une surface (5) d'un diamant (1) à l'aide d'un élément mécanique (3) qui est déplacé relativement à la surface (5) du diamant (1), des grains de diamant non liés (2) étant obtenus entre l'élément mécanique (3) et la surface (5) du diamant (1), l'élément mécanique (3) soumettant les grains de diamant (2) à un mouvement rotatif sur la surface (5) du diamant (1), de sorte que les grains de diamant (2) se déplacent relativement à l'élément mécanique (3) et à la surface (5) du diamant (1), l'élément mécanique (3) établissant ainsi un contact mécanique avec la surface (5) du diamant (1) par l'intermédiaire des grains de diamant (2), ledit contact mécanique représentant ainsi une longueur de contact (8) sur laquelle les grains de diamant (2) roulent sur la surface (5) du diamant (1), principalement selon le sens du mouvement relatif de l'élément mécanique (3) relativement à la surface (5) du diamant (1), les grains de diamant (2), avec l'aide de l'élément mécanique (3), venant presser au niveau de la surface (5) du diamant (1) tout en roulant, et des fissures microscopiques (6) étant ainsi créées au niveau de ladite surface (5), laquelle se désagrège progressivement.
