Abstract
The present invention presents a non-destructive method and means of obtaining either the inner portion or the outer contour of a two-dimensional or three-dimensional model of the outer contours of a gemstone. The method comprising the steps of placing the gemstone on a holder such that the gemstone to be scanned is located in a radiation path comprising inter alia at least one emitter and at least one detector synchronized by a processor; radiating said gemstone by means of said emitter; detecting the emitted irradiation by means of said detector; processing said detection such that a two-dimensional in-scan of said gemstone is obtained by means of said processor; displacing the gemstone in respect to said emitter and said detector; repeating steps (b) through (e) for a plurality of predetermined displacements; and, if a three-dimensional model is required, integrating the obtained multiple two-dimensional in-scans into a three-dimensional model of the gemstone'"'"'s outer contours; wherein the emitter is an irradiation delivery device, selected from a group consisting of either monochromatic or white light, UV or IR emitters; X-ray radiation source and/or collimator of the same; NMR, CT, NQR and/or MIR scatters; beta radiation emission devices; gamma radiation emission devices; laser beam cannons; photons cannons; microwave or RF emitters; sonic or ultrasonic emitters or any combination thereof.
