Zusammenfassung:The present invention includes the steps of: storing data such as the symmetry, the variation degree in the area, the displacement of a tip portion, the depth of a slit, the shoulder widths, and the like of eight heart marks and the symmetry, the variation degree in the area, the displacement or sharpness of an arrow tip, and the like of eight cupid marks into a computer database; and performing arithmetic processing of the data and ranking determination of the quality of the heart marks and the cupid marks. It is an object of the present invention to provide a method and device capable of objectively determining the quality on the basis of the same determination criterion using determination software in both of a case where the diamond is directly imaged by a CCD camera.
