Abstract
A machine (20) for bruting non- circular gemstones to a form wherein the bruted gemstone has at least one point comprising, a rotatable gemstone shaft (1) one end of which is adapted to have a gemstone to be bruted mounted thereon, a bruting tool (53) adapted to be brought into engagement with the gemstone in order to achieve bruting of the gemstone, and displacement means for displacing the bruting tool and/or the rotatable gemstone shaft (24) relative to a datum plane in synchronisation with the rotation of the gemstone shaft, the extent of displacement provided by the displacement means being directly related to the desired form of the bruted gemstone, the extent and timing of the displacement being such that when in use the point or points of the gemstone are directly prependicular to the datum plane, the gemstone is displaced out of contact with the bruting tool.
