    • Abstract
  • Dominican Republic is one of the main localities of ambers which contain the most inclusions of fossil organism. In the paper, the gemmological characteristics, I R absorption spectra, the micro-scale structure and differential thermal analysis thermogram of the ambers from Dominican Republic are tested by using conventional gemmological methods and the modern testing instruments such as infrared Fourier transform spectroscope, scanning electron microscope, differential thermal analysis and so on. At the same ti me, the ambers from Dominican Republic are also compared with the ambers from the other localities. The results show that the ambers from Dominican Republic are of the more colours and much cleaner in the interior. The ambers from the different localities may be of the same geological age, but exit the different FTI R absorption bands and strength according to the different polymeric grade.
