The ED-XRF, a non-destructive spectroscopic technique, uses an x-ray beam that illuminates the gemstone sample. This energy causes the material to emit x-rays and is used for:

  • Trace metal and transition metal determination
  • Determining chemical composition of a gemstone
  • Detection for a number of gemstone enhancements
  • Revealing whether staining or chemical impregnation has occurred in gemstones
  • Differentiating freshwater from saltwater pearls
  • Determining the origins of corundum and alexandrite
  • Determining the geological environment in which stones were formed
