In one embodiment, the viewer is mounted to employ the camera and LED light source of the personal communications device. The viewer directs the light from the light source as a light beam along a path incident to the surface of the gemstone containing the inscription. The gemstone spectrally reflects the light beam along a path back toward and through a magnifying lens to the camera lens of the personal communications device thereby enhancing the magnifying properties of the camera lens to produce a viewable light image that reveals the inscription on the viewing screen of the personal communications device. In another embodiment, the viewer is aligned to the front facing camera of the personal communications device, and includes its own light source. ## Claims ### Claim 1 A gemstone viewer for working with an electronic device having a camera lens, the gemstone viewer comprising: a base having an integral light source and a portal disposed in a bottom plane; one or more mirrors; a viewer lens; optically clear structure, with the viewer lens positioned between the optically clear structure and the camera lens; the optically clear structure and the viewer lens being held at a sufficient distance from each other such that the camera lens is properly focused through the viewer lens to the surface of a gemstone when the surface of the gemstone is placed against the optically clear structure; and the plurality of mirrors arranged to direct light from the integral light source off the surface of the gemstone to the camera lens. ### Claim 2 (depends on 1) The gemstone viewer of claim 1, wherein the base is removably secured to the electronic device. ### Claim 3 (depends on 1) The gemstone viewer of claim 1, further comprising a removable retaining ring for holding the optically clear structure in place, the optically clear structure being positioned to receive a gemstone on the optically clear structure. ### Claim 4 (depends on 1) The gemstone viewer of claim 1, further including a gemstone retention clip to secure a gemstone to the optically clear structure. ### Claim 5 (depends on 1) The gemstone viewer of claim 1, further including a cover associated with the base, wherein the viewer lens is connected to the cover. ### Claim 6 (depends on 1) The gemstone viewer of claim 1, wherein the integral light source is powered by a battery. ### Claim 7 (depends on 1) The gemstone viewer of claim 1, wherein the one or more mirrors are attached to the base. ### Claim 8 (depends on 1) The gemstone viewer of claim 1, further including a cover associated with the base, wherein the optically clear structure is connected to the cover. ### Claim 9 A gemstone viewer for working with an electronic device having a camera lens, the gemstone viewer comprising: a base having an integral light source powered by a battery, the base having a portal disposed in a bottom plane; one or more mirrors attached to the base; a focusing glass, and a viewer lens positioned between the focusing glass and the camera lens; the focusing glass and the viewer lens being held at a sufficient distance from each other such that the camera lens is properly focused through the viewer lens to the surface of a gemstone when the surface of the gemstone is placed against the focusing glass; and the plurality of mirrors arranged to direct light from the integral light source off the surface of the gemstone to the camera lens. ### Claim 10 (depends on 9) The gemstone viewer of claim 9, wherein the base is removably secured to the electronic device. ### Claim 11 (depends on 9) The gemstone viewer of claim 9, further comprising a removable retaining ring for holding the focusing glass in place, the focusing glass being positioned to receive a gemstone on the focusing glass. ### Claim 12 (depends on 9) The gemstone viewer of claim 9 further comprising a cover associated with the base, the viewer lens and the focusing glass being connected to the cover, and being held at a sufficient distance from each other by the cover such that the camera lens is properly focused through the viewer lens to the surface of a gemstone when the surface of the gemstone is placed against the focusing glass. ### Claim 13 (depends on 12) The gemstone viewer of claim 12, wherein the cover further includes a gemstone retention clip to secure a gemstone to the focusing glass. ### Claim 14 A gemstone viewer for use with an electronic device having a camera with a camera lens, the gemstone viewer comprising: a base having a portal disposed in a bottom plane; a light source positioned within the base; one or more mirrors positioned within the base; a cover, capable of fitting over the base; a viewer lens mounted within the viewer; a focusing glass connected to the cover, with the viewer lens positioned between the focusing glass and the camera lens when the cover is in position over the base; the focusing glass and the viewer lens being held at a sufficient distance from each other such that the camera lens is properly focused through the viewer lens to the surface of a gemstone when the surface of the gemstone is placed against the focusing glass; and the one or more mirrors arranged to direct light from the light source spectrally reflecting off the gemstone to the camera lens. ### Claim 15 (depends on 14) The gemstone viewer of claim 14, wherein the base is removably secured to the electronic device. ### Claim 16 (depends on 14) The gemstone viewer of claim 14, further comprising a removable retaining ring for holding the focusing glass in place. ### Claim 17 (depends on 14) The gemstone viewer of claim 14, wherein the cover further includes a gemstone retention clip to secure a gemstone to the focusing glass. ### Claim 18 (depends on 14) The gemstone viewer of claim 14, wherein the viewer lens is connected to the cover. ### Claim 19 (depends on 14) The gemstone viewer of claim 14, wherein the light source is powered by a battery. ### Claim 20 (depends on 14) The gemstone viewer of claim 14, wherein the one or more mirrors are mounted to the base.
