Gem Illuminated Spectroscope

Gemological spectroscopeseparates white light into its components spectral colors ranging from 400 to700nm. When a gem under a test is illuminated properly with white light andobserved through a spectroscope, chemical ingredients present in it absorb somewavelengths which are absorbed by the gem appear as dark lines or brands on thespectrum. Such spectral pattern is specific for certain types of stones andhelp to identify and separate from lookalikes.

Absorption spectrum givesan indication of the coloring elements present in the gemstone, therebyassisting in its identification. In some cases spectral pattern helps toseparate natural gemstones from their synthetic (dyed) counterparts.

A spectroscope for visiblelight shows the absorption lines of the elements involved in producing itscolor. For instance, it helps to separate ruby (chrome) against red or pinksapphire (iron). Spectroscope breaks up the light that is being transmittedfrom a gemstone to its spectral colors. The process allows the gemologist tosee the various wavelengths absorbed by the gemstone. Making this one of themost important tools in identifying gem. Spectroscopes allow you to analyze aloose or mounted stone and they also help to distinguish natural stones fromsynthetics by the stone a selective absorption of certain wavelengths.
