Hetian jade is oily and has little to do with the hot and cold weather. In summer, the temperature is high and sebum sweat is secreted. When playing with hetian jade, it will lead to a better sense of oiliness.

The oiliness of Hetian jade is closely related to its quality and surface polishing.

Generally speaking, the seed material of Hetian jade in Xinjiang is dense in texture and structure, and its oil feeling is obviously better than that of Russian material, Korean material, Qinghai material, Hetian mountain material and landscape material in Xinjiang.

In addition, the polishing process of jade surface also determines the oiliness. Soft polishing can make oil adhere to Hetian jade more easily, which is better than high polishing.
