The spectroscope is a tool of examining which parts of white light are absorbed by a gemstone(as well as by other materials).Materials can absorb parts of the electromagnetic spectrum,and when the absorbed parts fall within the visible range,that absorbed part will influence the color of the material.When a gemstone is observed with a spectroscope,the absorbed parts show as dark lines and/or bands in the spectroscope image.There are two types of spectroscopes used in gemology:diffraction grating spectroscopes(Based on diffraction) Prism spectroscopes(based on dispersion)
