    摘要： A system for grading the cut of a diamond utilizes a number of appearance metrics to generate scores for a number of cut components that affect cut quality. These cut components include brightness, fire, scintillation, overweight, durability, polish, and symmetry. The cut grading system employs a cut grading algorithm that processes the individual scores obtained for the cut components to generate an overall cut grade for the diamond. The scoring methodology and the cut grading algorithm are designed to emulate actual observation grading such that the overall cut grade represents a fair indication of the cut quality of the diamond. In one practical embodiment, the cut grading system is fully automated and computer-implemented.

    摘要： The invention is a multicolored reflecting surface that can be mounted beneath a lens for facilitating the grading of a gemstone's brightness and symmetry. The multicolored reflective surface may be a disc that has an opening or aperture surrounded by multicolored concentric rings through which the gemstone is viewed on the object side of the lens. Alternatively, the multicolored reflective surface may be a cylinder formed of multicolored bands through which the gemstone is viewed. Light reflecting from the multicolored rings or bands creates specific colors on the gemstone that allow symmetry and brightness of the stone to be evaluated.

    摘要： The invention is a multicolored reflecting disc that can be mounted to a lens for grading gemstone brightness and symmetry. The disc has an opening or aperture through which the gemstone is viewed on the object side of the lens. The aperture is surrounded by multicolored concentric rings which face the gemstone. Light reflecting from the multicolored rings creates specific colors on the gemstone that allow symmetry and brightness of the tone to be evaluated.
