    摘要： The invention relates to method for computing a unique identifier for a gemstone, comprising:
    - acquiring a 2D digital master image (MI, MIn, MIw) of the gemstone, where an image of a reference mark (56) on the gemstone defines a master image referential (OR, XR, YR);
    - matching a virtual selection mask with the master image according to a predefined position and orientation with respect to the master image referential;
    - defining, in the master image, a plurality of distinct selected zones (SZ') corresponding to the location of selection zones of the matched mask;
    - detecting, in each of the plurality of distinct selected zones, the presence or not of at least one facet edge portion image;
    - defining a location of the detected facet edge portion images in the master image;
    - computing a unique identifier based on the defined locations of the detected facet edge portion images.

    摘要： A rapid identification method of Argyle diamond's origin by characteristic Raman spectra, comprising steps of:
    providing a Raman spectrometer to collect Raman spectra of multiple sample diamonds under conditions of 785 nm laser excitation, 450mw laser power, 250 - 2350 cm- 1 Spectral Range, spatial resolution >100 µm, and 0.2-3 seconds integration time; and
    the sample diamonds being identified as type A and type B on the basis of diagnostic features of Raman raw spectra;
    wherein Raman raw spectra of type A diamonds showing diamond's C-C bonds at 1332 cm-1 protrude on a convex-shaped background, and when raw data of type A diamonds are processed by a background correction and normalization program, eight distinctive peaks at 640 cm-1, 832 cm-1, 952 cm-1, 1012 cm-1, 1225 cm-1, 1834 cm-1, 1940 cm-1, 2120 cm-1 are shown up in the spectrum, in addition to the C-C mode at 1332 cm-1, the eight peaks being interpreted as fluorescent peaks excited by the incident near-infrared 785 nm laser beam and defining the type A diamonds as Argyle pink diamonds; and when Raman raw spectra of type B diamonds are processed by the background correction and normalization program, eight distinctive peaks at 302 cm-1, 339 cm-1, 640 cm-1, 952 cm-1, 1012 cm-1, 1250 cm-1, 1273 cm-1, and 1565 cm -1 are shown up in the spectrum of type B diamonds, whereby defining type B diamonds as Argyle pink diamonds.

    摘要： Systems and methods for mobile gemstone identification are described herein. According to an embodiment, a mobile gemstone identification system (100) includes a gemstone holder (104, 202, 302, 402) to hold a gemstone (102) and includes an optoelectronic assembly (106). The optoelectronic assembly (106) includes an illumination device (108) to illuminate the gemstone (102) by causing radiations to be incident on the gemstone (102). Further, the optoelectronic assembly (106) further includes a screen (110) to form a pattern indicative of an optical response of the gemstone (102), in response to the radiations being incident on the gemstone (102).

    摘要： A method and apparatus for orientating discrete objects, such as gemstones, is described. The method comprises providing the objects on a travelling path; providing a pair of opposed walls (38) extending generally along the direction of the path; and generating relative oscillatory movement (14) between the pair of walls (38) and the travelling path (in a direction generally transverse to the direction of the path), so that the pair of walls (38) imparts lateral force to the objects to thereby urge them into their most stable orientation as they progress along the path. A device for checking the orientation of the discrete objects is also described.

    摘要： A method and apparatus for generating a 3D model of and/or detecting inclusions in a polished gemstone such as diamond is described. The gemstone (103) is rotated in a series of discrete increments. At each rotational position of the gemstone, the gemstone (103) is illuminated with collimated light (111,112) and a silhouette image recorded. At each rotational position, the gemstone (103) is also (before further rotation) illuminated with diffuse light (109), and a diffuse image recorded. The images are analyzed to obtain a 3D model of the surface of the gemstone. Features may then be identified in the diffuse images and tracked between subsequent diffuse images. The tracked features may be located relative to the 3D model of the gemstone, taking into account reflection and refraction of light rays by the gemstone. Some or all of the located features may then be identified as inclusions.
