ABSTRACT:
A system for identifying jewels comprises an automatic microscope 2, an automatic image-analyzing apparatus 3, an electric-resistance measuring apparatus 4, a weighing apparatus 5, a spectroscopic-analysis apparatus 6, and an electronic information processing apparatus 7. The microscope 2 forms an enlarged image of an identification number 11d marked on a jewel to be identified. The image-analyzing apparatus 3 receives the image of the identification number 11d from the microscope 2, and analyzes it. The measuring apparatus 4 measures the electric resistance between spots 11a and 11b marked on the jewel. The weighing apparatus 5 determines the specific gravity of the jewel to the nearest 0.001 gram. The spectroscopic-analysis apparatus 6 directs a beam of light of particular band on a spot 11c marked on the jewel, and determines the spectrum of the light reflected from the spot 11c. Electric signals to represent the results of measurements conducted in the apparatuses 3, 4, 5, and 6 are output to the processing apparatus 7, which processes these signals and store them in memory.
