    • Abstract
  • The freshwater cultured pearls are classified according to the colour and investigated by Fourier transform infrared spectroscopy(FT-IR),plasma emission spectrometry, Raman spectrum and X-ray powder diffraction(XRD) to research their organic and inorganic compositions. The trace metal elements and carotenoids have influence on the colour of the freshwater cultured pearls.
