Why Use Ultraviolet Light?

An ultraviolet lamp that provides the proper intensity of longwave and shortwave ultraviolet light can be invaluable as a means to:
  • Separate natural diamond from synthetic "gem quality" diamond.
  • Separate diamond from colorless sapphire and zircon (natural and synthetic).
  • Distinguish natural emerald from synthetic.
  • Test emeralds for oiling, and reveal what the oiling process has concealed.
  • Distinguish older synthetic blue sapphire from natural blue sapphire.
  • Detect heat-treated blue sapphire.
  • Ensure proper grading of diamonds.
  • Differentiate among pink topaz, pink sapphire and pink tourmaline.
  • Separate:
    • Natural tanzanite from imitation tanzanite.
    • Lapis from dyed jasper.
    • Reddish-brown amber from plastic look-alikes.
    • Blue zircon from aquamarine.
    • Natural black pearl from dyed black pearl.
    • Natural black opal from sugar-treated black opal.
