supporting a gemstone on a flat stage, wherein the stage is capable of transmitting UV to visible light, and wherein the gemstone is backed by an absorption material;
causing a light beam to emit from a light source, the light beam within a first range of wavelengths, aimed at a first dichroic beam splitter toward the flat stage,
wherein the first dichroic beam splitter is configured to reflect light of the first range of wavelengths and pass light of a second range of wavelengths; and
capturing a fluorescence image of the gemstone on the flat stage by a digital camera aimed at a second dichroic beam splitter configured to reflect light of the second range of wavelengths that pass through the first dichroic beam splitter.
