Abstract
Gemologists consider the mineral beryl, beryllium aluminium silicate, to be the gem, emerald, when it contains sufficient chromium, > 0.1%, to colour it a strong green. Emeralds usually contain other trace elem ents. To investigate the feasibility of distinguishing an emerald's co untry of origin through its trace content, the trace elements in emera lds and a few beryls from sixteen locations have been determined with a single nondestructive measurement using PIXE and PIGE. From the data base established with this limited number of samples, distinguishing t race element patterns were found.
