The name of Lantian jade was first seen inHanshu·Geography”, and the beautiful jade was produced inBeijing (now Xi’an) North Lantian Mountain”. Afterwards, ancient books such asThe Book of the Later Han Dynasty · Biography of the Foreign Relations”, Zhang Heng’sXijing Fu”, “Guang Ya”, “Shui Jing Zhu” og “Yuanhe Prefectures and Countiesand other ancient books have recorded the production of jade in Lantian. During the Wanli period of the Ming Dynasty, Song Yingxing stated in Tiangong Kaiwu: “The so-called Lantian is an alias for jade from Congling (Kunlun Mountain), and then he mistakenly thought that Lantian was the Lantian of Xi’an.

In recent years, geologists in Shaanxi have discovered serpentinized marble jade in Lantian, and believe that it is the Lantian jade recorded in ancient times. This discovery not only attracted the attention of the geological community, but also aroused the interest of archaeologists. Although this kind of jade is not very beautiful, because Lantian is located near the ancient city of Xi’an, with a Mohs hardness of about 4, it is easy to process, so the ancients are likely to use it as an ornament. Among the jade articles of the Han Dynasty, there are two pieces that resemble today’s Lantian jade: one is a large jade shop head unearthed near the Mao Tomb of Emperor Wu of the Han Dynasty in Shaanxi, and the other is a Han Dynasty jade pendant from the Palace Museum. Many scholars believe that the quality and color of these two jade articles are very similar to the Lantian jade discovered in recent years. Imidlertid, whether they are really thelantian jadethat the Dai referred to requires further investigation.
