摘　　要：对近期市场上出现的一种绿松石的仿制品进行常规宝石学特征、红外吸收光谱、X荧光能谱、紫外-可见光光谱研究。研究结果表明：该绿松石仿制品为硅孔雀石,莫氏硬度为4,密度为2.3g/cm^3,整体呈蓝色,宝石显微镜下可见蓝色斑点,结构致密。红外吸收光谱显示硅孔雀石的特征吸收光谱。X荧光能谱测试蓝色部位主要含有Cu、Si,黑色部位还含有Mn。紫外-可见光光谱测试具有635-700nm的宽吸收。该样品的蓝色主要由Cu引起。A kind of turquoise imitation on the recent market has been studied through ge-mological characteristics,infrared absorption spectroscopy,X fluorescence spectroscopy and UV-Visible Spectroscopy.The result shows that the imitation is chrysocolla with MOHS Hardness of 4 and density of 2.3g/cm^3.It is in blue color with a compact struc-ture,and the blue spot is visible under the microscope.Infrared absorption spectrum showed characteristic absorption spectrum of chrysocolla.X-ray fluorescence spectroscopy result shows that the blue part is consist mainly of Cu and Si and the black part consist of Mn as well.UV-visible spectra shows a broad absorption of 635-700nm.The blue color of the sample is caused by Cu.
