Gemstones are identified by gemologists

Who describe gems and their characteristics using technical terminology specific to the field of gemology.
Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum.
