White jade is interwoven into a unique felt-like structure by extremely fine tremolite minerals, so the surface is delicate and moist, with a characteristic grease-like luster. This phenomenon has not been found in other jade and can be used as a distinguishing mark. The apparent degree of grease gloss is related to the microstructure of white jade, that is, it has a certain relationship with the place of origin. In general, the white jade produced in Xinjiang has a strong luster, and the white jade produced in Qinghai is poor. The white jade produced in Russia is somewhere in between. By comparing white jade with other jade, the grease luster can be easily identified.
