UV-VIS-NIR Spectrum of Jadeite Jade from Burma

More Information
  • Received Date: August 19, 2003
  • UV-VIS-NIR spectra of jadeite jades with different colours from Burma have been tested. The results show that the spectra of jadeite jades with different colours have different characteristics, reflecting the difference of colouration, and the absorption peak of 437 nm occurs in the various jadeite jades. The results show that (1) the absorption of 437 nm peak caused by Fe3+ ion is most common and can be seen in jadeite jades with various colours, but it is the most weak in the green and the deep green jadeite jades; (2) the role of Fe3+ ion is different from that of Cr3+ ion, it has no substantive influence on the colour of jadeite jade; (3) the experiment has not found the evidence of Fe2+ existing in the jadeite jade from Burma; (4) Cr3+ ion is the colouring agent of green jadeite jade; (5) the hypothesis of Mn3+ ion as the colouring agent can explain various characteristics of UV-VIS-NIR spectrum; (6) UV-VIS-NIR spectra of jadeite jades treated by bleaching and plastic impregnation and dyeing are different from that of the untreated, and can be regarded as diagnostic features.
