1. A method for determining a relationship between at least two gemstone samples, the method comprising:
illuminating a first gemstone sample with illuminating light of at least one fluorescence-exciting wavelength range;
detecting and recording a corresponding at least one first fluorescence-emission light spectrum emitted from the first gemstone sample;
illuminating a second gemstone sample with the illuminating light of the at least one fluorescence-exciting wavelength range;
detecting and recording a corresponding at least one second fluorescence-emission light spectrum emitted from the second gemstone sample;
analyzing the at least one first fluorescence-emission spectrum and at least one second fluorescence-emission spectrum; and
determining a relationship between the first and second gemstone samples;
wherein said analyzing of the at least one first fluoroescence-emission spectrum and at least one second fluorescence-emission spectrum comprises at least one of the following:
independently analyzing the first and second fluoroscence-emission spectrums and respectively generating first and second fluoroescence-signatures, then utilizing the first and second fluorescence-signatures to determine the relationship between the first and second gemstone samples;
applying a direct comparison between the first and second fluorescence-emission spectrums and generating fluorescence comparison identifiers, then utilizing the comparison indentifiers to determine the relationship between the first and second gemstone samples.
