ABSTRACT:
A method, and product from the method, of faceting a gemstone in which the facets, when combined with the polishing
on-polishing of the facet form an image such as the Star-of-David. The image is visible when viewed through the table of the gem. On one end of a clear or substantially clear gemstone, a series of facets are made which combine to create lines and boundaries. Through selective polishing of the facets, usually as they are made, some of the facets so created are darker and more visible than the others. These darker facets assist in forming the Star-of-David, or other image, visible through the table of the finished gemstone.
