The Synthetic Experimental Study Of The Imitated Chicken-Blood Stone

Recent years, the chicken-blood stone becomes popular in the market. With people's increasing demand, high-quality raw materials were in short supply. Therefore, a wide variety of imitation appeared on the market and the customer and collectors'profits were hurt. The imitated blood stone was studied in this context. The optic characters, structure and components of the sample were analyzed with the instruments such as XRF, XRD, FTIR, polarized microscope, etc. The imitated blood stones were synthesized under normal temperature and standard atmosphere, normal temperature and high pressure with chlorite, pyrophyllite, kaolinite, organic adhesive and organic dyes in our lab.The results show that the density and refractive index of the sample is lower than the natural's. The main components of the natural's terra are kaolinite and pholerite. The natural's blood is cinnabar. The imitated bloodstone from the market was mainly composed of chlorite. The red part of the imitated blood stone was caused by the appending gules organic pigment. The imitated blood stone was pressed with triturated chlorite interfused with the pigments as we observed under the microscope. The gemstones parameters of the imitated blood stone we made were detected and compared with the imitation found on the market. The results show that the gemstones parameters of the imitated blood stone we made are similar with the ones from the market. The experiment proposed in this paper provides not only a possible way of the imitated blood stone but also a method to the identification of the imitation.
