ABSTRACT:
A device for holding and positioning stones that are being prepared for invisible set jewelry. The device includes an automatically cooled blade and a holding member for holding the stone wherein the position of the stone may be adjusted linearly and angularly about a plurality of orthogonal axes. A base is coupled to three orthogonal translation stages for linearly adjusting the location of the stone with respect to the blade. Further, the base is rotatably coupled to the linear translation stages thereby enabling the linear translation stages to rotate about a first axis of rotation which is orthogonal to the top planar surface of the base. A mounting arm is pivotally coupled to the linear translation stages about a second axis of rotation parallel to the planar surface of the base. The mounting arm includes stone holding means for securing the stone which is rotatable about a third axis of rotation transverse to the first and second axes and which provides linear adjustment to position the stone within the mounting arm. The mounting arm is further pivotable about a fourth axis of rotation orthogonal to the second axis of rotation. Finally, the mounting arm pivots about a fifth axis of rotation parallel to the first axis of rotation for raising and lowering the stone onto the cutting surface of the blade.
