ABSTRACT:
Tools for setting precious and semi-precious stones in metal, and methods for using such tools to set such stones quickly and to accomplish such setting in the absence of chisel marks in the finished products. A first tool includes a disc-shaped rotating grinding member that has a beveled cutting edge for trimming excess metal prior to making the setting. A second tool has a disc-shaped rotatable cutting member having a kerfed cutting edge that produces parallel channels in such metal to thereby define a linear bar means therebetween which bar is manipulated by a conventional tool to form beads that retain the stones within their respective settings. The inventive method contemplates the use of the beveled edge tool to form beveled reflective surfaces on opposite sides of the stone, and use of the kerfed-edge tool thereafter to form the bead-producing bars. An alternative method contemplates using the kerfed edge tool first, followed by the beveled edge tool. In both methods, the preparatory steps are performed before the stones are set in their respective mounting holes.
