Duties vary from one position to another in this occupation but, in general, gemmologists:

  • identify different types of gemstones (for example, diamond, emerald, jade, ruby, topaz) and their synthetic counterparts
  • differentiate between natural gems and stones that have been treated to enhance their colour or clarity or to stabilize them 
  • grade gemstones and pearls.

To identify gems, gemmologists may:

  • examine surface and internal characteristics under magnification using a loupe or microscope
  • use equipment such as a polariscope, dichroscope or polarising filter to detect optical characteristics  
  • measure refractive indices and, in some cases, interpret optical character and optic sign
  • analyze absorption and fluorescent spectra
  • measure specific gravity (for example, by using hydrostatic or heavy liquid immersion techniques or by using calibrated measuring tools and calculating the weight of mounted stones)
  • use other sophisticated testing procedures to identify synthetic and treated gem materials.

Depending on where they work, gemmologists may have a variety of additional responsibilities. For related information, see the Jeweller occupational profile.
