"lantian jade" is named after being produced in Lantian Mountain in the north of Xi 'an. But later, probably because the mine was mined out, it could not be found all over the world, and it was questioned that Lantian was only a distribution center for jade, not a jade producing area. 1978, geologists discovered serpentine marble in Lantian County, Shaanxi Province. Compared with the cultural relics unearthed in Han Dynasty, they think it is probably lantian jade recorded in ancient times. Although it is still controversial whether ancient lantian jade is today's "lantian jade", most scholars, such as Zhou Nanquan and Luan, think that lantian jade described in ancient books such as lantian jade and Hanshu was discovered today. The famous lantian jade in ancient China was produced in Lantian, and its jade was serpentine marble. Its main mineral composition is calcite, followed by sphalerite. The color is mainly white, but also yellow, beige, light green to green. Fine texture and good processability. Lantian jade, mined in Lantian County today, has been carved into various handicrafts, such as tea sets, wine sets, jade pillows, jade bracelets and fitness balls, which are sold all over the country.
Li Shangyin's poem "Mermaids shed pearl-like tears on the moon-green sea, and blue fields breathe their jade on the sun" created lantian jade in Shaanxi. Lantian jade brand "Jade Warming Lantian" comes from this famous poem!
