This paper proposes computer-aided design modules for automatic setting and arranging of gemstones and diamonds on the head of a halo ring. These modules are able to automatically set the center stone, side stones, and accent stones by using a set of inputs from user. To develop the mentioned modules, the authors have studied several key parameters: sizes and cuts of center stones, side stones, and accent stones, distances between stones, sizes and shapes of prongs, including shrinkages and

These mathematic models were further used in the development of the computer-aided design modules based on RhinoScript Platform in the Computer-Aided Design (CAD) software named Rhinoceros. The module was developed for assisting CAD designers to automatically generate gemstone rings and to set and arrange center stone, side stones, and accent stones on parts of the rings. It was developed using data and information about jewelry ring design from jewelry designers and a manufacturer, as well as, collaborating with the manufacturer for testing the developed module. The proposed module can help CAD designer to reduce gem setting and arrangement time by about 67-70% in comparison to the manual method. The results and details of the development of the module and the development of the proposed generative design system were included in this paper.
