A viewing device is configured to magnify and view a marking on a gemstone. The viewing device includes a light source, a mask, a magnifying optical device, and a camera. The light source generates light directed along a first path towards the gemstone. The mask partially obscures the light from the light source to generate a pattern. The partially obscured light is reflected off of the gemstone and magnified by the magnifying optical device. The camera is positioned to capture the magnified light. One or more additional light sources generate light directed along a second path towards the gemstone. The light enters the gemstone through a preferred facet and internally reflects. Internally reflected light scatters off of an internal mark in the gemstone and exits the gemstone through the gemstone's top face. The reflected and scattered light is magnified by the magnifying optical device and captured by the camera.
