Colorimetry Study on Red Tourmaline Color Genesis
In this paper,the colorimetry characteristics of ten red tourmaline samples were studied through the visible light spectrometer Color I5 of X-rite company of the United States.In order to give a quantitative description of the color of red tourmalines,the chromaticity index of the samples was measured,and the red tourmaline color parameters with possible principle and technology for evaluation were obtained,including chroma coordinates,main wavelength,chroma,brightness,curves of reflection rate and chroma figures.Combining with the electron probe microanalysis and the chemical analysis,the relationship between the content change of color-caused ions and the color parameters was discussed by analyzing the existing states and content of color-caused ions Mn2+(ion),Cr3+(ion) and Fe2+(ion).
