A method for assembling a stone on a setting support, the stone being cut to exhibit a table, a crown, a girdle and a pavilion, including the steps of: providing a substrate coated with a pattern including an electrically conductive layer covered with a resin layer, the pattern having an inner contour delimiting a hole through the coated substrate and an outer contour corresponding to the outer contour of the desired setting support; removing the resin layer; after dissolution of the resin layer, positioning the stone in the through hole, the stone resting on the electrically conductive layer; and electrodepositing a metal layer on the electrically conductive layer to form the setting support, in order to make the stone integral with the metal layer.

A single-crystal diamond having a first facet plane is prepared. The single-crystal diamond is fixed to the support based on the first facet plane. An X-ray image of the single-crystal diamond is captured, the X-ray image being an X-ray image in which a crystal orientation of the single-crystal diamond is associated with an X-ray emission direction by associating the support to which the single-crystal diamond is fixed with the X-ray emission direction. A position of an inclusion of the single-crystal diamond in the single-crystal diamond is specified based on the X-ray image. It is determined whether or not a shape of the diamond tool intermediate is extractable from the single-crystal diamond with the inclusion being not included in an inclusion-excluded region. The shape of the diamond tool intermediate is extracted from the single-crystal diamond with the inclusion being not included in the inclusion-excluded region.

A cam follower is provided. The cam follower includes a polycrystalline diamond element, including an engagement surface. The engagement surface of the polycrystalline diamond element is positioned on the cam follower for sliding engagement with an opposing engagement surface of a cam. The cam includes at least some of a diamond reactive material.

A mounting holds a grooved gemstone invisibly to a setting. One end of the mounting has arms or extensions to receive the gemstone and protrusions extending inwardly from the arms to fit in the grooves of the gemstone, the mounting further comprising a holding configuration for holding the mounting to the setting. Insertion of the mounting into the setting may in one version distort the holding configuration and levers the arms to press harder into the groove.

Disclosed are a drill bit for drilling and a method for manufacturing same, in which the hardness of a body part of a shank can be selectively improved by performing rapid cooling in a forced cooling method after performing rapid heating selectively only on the body part of the shank in a high-frequency induction heating method after completing infiltration.
