DEF

Originally the person who set the rough or prepared diamond into a dop for sawing, bruting, and polishing. Today, the term commonly refers to one who sets the stones in sawing dops, but it may also be used to describe the technician who positions diamonds in automated polishing machines.

CONT

Now the marked stone can be set. This is usually done by setters (mostly female workers) who choose the appropriate "pot" in which the stone can be set. ... When the cement is ready, the setter places the stone, after having carefully examined its crystallisation, in a pot filled with cement.

CONT

La pierre marquée peut alors être sertie. Ce travail, habituellement, est fait par une femme qui choisit le «pot» convenant le mieux pour fixer la pierre et prépare le liant qui la sertira. [...] Une fois le mélange fait, la sertisseuse, après en avoir bien observé la cristallisation, dépose la pierre dans le pot préalablement rempli de plâtre.

OBS

Initialement, désignait la personne qui fixait le diamant brut au dop en vue du sciage, du débrutage ou de la taille. Ce terme désigne aujourd'hui la personne qui sertit le diamant dans le dop de sciage, et parfois, le technicien qui monte les diamants dans les machines de taille automatique.

  • Industrial Tools and Equipment
  • Gemmology
CONT

... you can see the basic set up of a traditional jamb peg faceter. The spinning lap provides the grinding and polishing surface, the wooden "dop" sticks to which the rough is adhered, serve to hold the stone in position as various cuts are made. The angle of the cut is controlled by placing the dop stick in a particular hole, the depth of cut is controlled by the amount of time the piece spends in contact with the lap and how hard the facetor presses down on it, and the radial position is controlled by removing, slightly rotating, and reinserting the dop stick in its hole as each different cut is made. Most stones that are cut on such equipment are referred to as "native cut. "

CONT

Although modern highly engineered faceting machines have replaced jamb pegs in much of the world, these older systems are still widely used, and a substantial proportion of the gems in commerce today have been cut by them.

DEF

Cône renversé [ou plateau] comportant des encoches, placé à côté de la meule, et destiné à maintenir constante l'inclinaison du bâton.

CONT

La taille nécessite d'encimenter la pierre au bout d'un bâton dont l'inclinaison sur la meule est maintenue constante par appui sur un évent (sorte de cône renversé comportant une série d'encoches, fixé verticalement à côté de la meule).

OBS

Subject field(s)
  • Industrial Tools and Equipment
  • Diamond Industry
DEF

A mechanical diamond holder attached to a tang which allows the polisher to change a diamond's position without removing it from the dop, thus keeping polishing angles constant.

CONT

The use of semi-automatic dops for polishing has made it necessary for the bruted band to have very straight sides, from the table to the desired width of the girdle, if not it will fall from the polishing pots.

French

Domaine(s)
  • Outillage industriel
  • Industrie diamantaire
DEF

Dop mécanique fixé à la pince, de sorte que le tailleur puisse changer l'orientation du diamant sans l'enlever du pot et garder ainsi les angles de taille constants.

CONT

En raison de l'emploi des «dops semi-automatiques» dans la taille et le polissage, il est impératif que la bande débrutée d'une pierre présente des bords impeccablement rectilignes, faute de quoi elle échappera de la pince utilisée pour la polir.
