Study on the Vibrational Spectra Characterization of the “She tai cui” Jade
The gemological testing methods, infrared absorption spectrum, Raman spectrum and X-ray powder diffraction were employed to study the gemological characteristics, spectral characteristics and structural features of the “She tai cui” jade. It is indicated that most “She tai cui” jade has the refractive index in the range of 1.53 to 1.54, and a density of 2.65~2.79 cm-1, and the hardness of 6.5 to 7 in addition to the low hardness (<5) for the pure white one. The mineral constitution is dominated by quartz in most of the “She tai cui” jade, except the white one, which is dominated by dolomite (about 63.91%). The former may contain a certain amount of other impure minerals and is attributed to the quartzite jade, while the latter contains a certain amount of SiO2 (about 34.85%) and a trace amount of calcite and albite, and is attributed to the dolomite jade.
