(2006/0196858) discloses a light source (Fig. 5, Ref. 176) configured to generate light directed along a first path (See Fig. 5) toward the gemstone (Fig. 5, Ref. 120); a mask (Fig. 5, Ref. 180; The ring shaped illuminator head blocks light to produce annular shaped illumination beam; Para. 0059) configured to partially obscure the light from the light source (Fig. 5, Ref. 176) to generate a pattern (annular shaped light beam), wherein the partially obscured light is reflected off the gemstone (Fig. 5, Ref. 120); a magnifying optical device (Fig. 5, Ref. 162) configured to magnify light reflected off the gemstone (Fig. 5, Ref. 120) along a second path (Fig. 5, Ref. 164); and a camera (Fig. 5, Ref. 166) positioned to capture the magnified (Fig. 5, Ref. 162) light such that the pattern (Fig. 5, Ref. 182) is captured by the camera (Fig. 5, Ref. 166) when a table (See Fig. 5, Ref. 120, Top flat surface of gemstone) of the gemstone (Fig. 5, Ref. 120) is oriented such that the marking is orientated to be captured by the camera (Fig. 5, Ref. 166)(Para. 0056). PNG media_image1.png 730 533 media_image1.png Greyscale Claim 2 Barron et al. (2006/0196858) discloses the gemstone (Fig. 5, Ref. 120) is oriented such that the marking (Para. 0058; indicium) is orientated to be captured by the camera (Fig. 5, Ref. 166) when the gemstone (Fig. 5, Ref. 120) is substantially flat (See Fig. 5). Claim 3 Barron et al. (2006/0196858) discloses the gemstone (Fig. 5, Ref. 120) is substantially flat (See Fig. 5) when light entering (Fig. 5, Ref. 182) the magnifying optical device (Fig. 5, Ref. 162) is substantially normal to the table (Fig. 5, top flat surface) of the gemstone (Fig. 5, Ref. 120). Claim 4 Barron et al. (2006/0196858) discloses the light source (Fig. 5, Ref. 176) is coherent (Para. 0069; broadband illuminator). Claim 6 Barron et al. (2006/0196858) discloses the first path (Fig. 5, Ref. 182) and second path (Fig. 5, Ref. 164) at least partially overlap extending in and out of the table (Fig. 5, Ref. 120; top flat surface of diamond). Claim 7 Barron et al. (2006/0196858) discloses an objective lens (Fig. 4, Ref. 118) through which the first and second path overlap (See Fig. 4, arrows); and a beam splitter (Fig. 4, Ref. 116) configured to reflect light from the light source (Fig. 4, Ref. 42) along the first path through to toward the gemstone (Fig. 4, Ref. 120). Claim 8 Barron et al. (2006/0196858) discloses the light source is a first light source (Fig. 4, Ref. 42), further comprising a second light source (Fig. 4, Ref. 134) that transmits light along a third path that extends through a facet (Fig. 4, Ref. 120; side of gemstone) of the gemstone (Fig. 4, Ref. 120) and the second path extends out of the table of the gemstone (Fig. 4, Ref. 120; top surface of the gemstone), the facet (side of gemstone) different from the table (top surface of gemstone). Claim 9 Barron et al. (2006/0196858) discloses the light source is a first light source (Fig. 4, Ref. 42), and further comprising: a second light source (Fig. 4, Ref. 134), different from the first light source (Fig. 4, Ref. 42) configured to illuminate the gemstone (Fig. 4, Ref. 120) when the camera captures (Fig. 4, Ref. 128) an image of the marking (Fig. 4, process monitoring unit Ref. 56). Claim 10 Barron et al. (2006/0196858) discloses the marking is an inscription (Para. 0048; indicium). Claim 11 Barron et al. (2006/0196858) discloses the inscription is on the surface of the gemstone (Para. 0048; indicium). Claim 12 Barron et al.

Claims 5, 15 Barron et al. (2006/0196858) discloses the claimed invention except for the light source is a light emitting diode or a mask can be from a projection from a digital programmable display. It would have been obvious to one having ordinary skill in the art at the effective filing date of the claimed invention was made to combine Barron et al. (2006/0196858) with the different optical elements listed above since it was well known in the art that using such optical elements such as a LED or digital programmable display improves durability and adaptivity for different applications, therefore making the device more marketable.
