Abstract: Systems and methods for determining properties of gemstones based, inter alia, on fluorescence properties of the gemstones, are presented. In one aspect, properties of at least one gemstone can be determined. In another aspect, a relationship between at least two gemstones can be determined. In one example, a first and a second gemstones are illuminated with illuminating light of at least one fluorescence-exciting wavelength range; corresponding at least one first fluorescence-emission light and at least one second fluorescence-emission light spectrum, emitted from the first and second gemstones respectively are detected and analyzed, either independently or by comparison, to determine the relationship between the first and second gemstones. In some examples, data indicative of visible light absorbance or three-dimensional models of the gemstones is combined with the fluorescence data to determine the properties or the relationship.
