Hetian jade is one of the "Four Famous Jades of China." In the traditional narrow sense, it refers to jade from the Hotan region of Xinjiang, best known for Hetian "Ziliao" (river-worn material). Broadly, Hetian jade refers to nephrite (true jade). Hetian jade is named after Hetian, Xinjiang Uygur Autonomous Region, but it is not a regional concept itself. It doesn't just refer to jade from the Hotan region of Xinjiang; it's a type of product name. China names all stones with over 98% tremolite content as Hetian jade, and all are within the national standard. ■ Due to the shooting environment, the color of the photo may look slightly different from the actual product.
