    Abstract: A method is provided wherein a wax-like starting material is worked to obtain a prototype of an ornament, such as a ring, which working of the starting material takes place while the starting material is fixed in place on a manipulable holding fixture. The operations are carried out in at least one Cartesian coordinate (x,y,z) direction as well as in at least one cylinder coordinate (x,r,?) direction, while the starting material is fixed in place on the same holding fixture. This procedure makes the method easier and quicker to carry out, and permits the production numbers therefore to increase, while decreasing the cost price per product.
