Serpentine jade, also known as serpentine, is an important member of the Chinese gem family and the first jade species to be discovered and used. According to archaeological discoveries, humans have been in the Neolithic age about six to seven thousand years ago. Start using serpentine jade stone tools. Mosquito-patterned stone jade has been valued by the past dynasties and can be called “the light of ancient jade, the treasure of ten thousand years.” From the earliest jade products in China to the largest jade products in the world, as well as many contemporary jade carvings known as national treasures, they are all made from serpentine.

As far as the current jade market is concerned, serpentine jade jewelry still accounts for a large proportion of low-grade jade. Serpentine jade is widely used in China, and serpentine jade ornaments such as jade bracelets, jade pendants, and jade ornaments still have a considerable market. 伝統的に, serpentine jade is also called Xiuyu, named after the place of origin in Xiuyan County, Liaoning. しかし, names such as Xinyi jade, Luchuan jade, and Taiwan jade appeared in some places. These names often cause confusion in the market and make buyers unable to understand their essence. したがって, the national standard stipulates that gem-grade serpentine graphite is named uniformly with “serpentine”, and the place of origin does not intervene in the naming. Only Xiuyu can be named separately as a variety of serpentine jade.
Serpentine jade is mainly produced in China. 加えて, the United States, New Zealand, Mexico, and North Korea are also famous producing areas.
