Gemstone tester and a method of characterising a gemstone

摘要

A gemstone tester for characterizing a gemstone and a method of characterizing a gemstone are provided, the gemstone tester comprising a detector unit for detecting one or more transmittances of the gemstone; and a processing unit for determining a first parameter based on one or more of the transmittances of light; and for characterizing the gemstone based on the first parameter; wherein each transmittance of the gemstone is a fraction of light of a specific wavelength that is passed through the gemstone.

1. A gemstone tester for characterizing a gemstone, the gemstone tester comprising:
a detector unit for detecting a plurality of light transmittances through the gemstone, wherein each light transmittance of the plurality of light transmittances is a respective fraction of light of a different wavelength that has passed through the gemstone; and a processor configured to:
determine a first parameter based on a first light transmittance;characterize the gemstone as a gemstone type based on the first parameter;determine a second parameter based on a ratio of a second and a third light transmittance if the processor cannot determine the gemstone type based on the first parameter; andcharacterize the gemstone based on the second parameter.
