Chinese Jade is jade that was specifically mined in China, and is the primary hardstone used in Chinese sculpture. The English term "jade" is used to translate the Chinese word yu, which in fact refers to a number of minerals including nephrite, jadeite, serpentine and bowenite, while jade refers only to nephrite and jadeite. Nephrite is found within metamorphic rocks in mountains, and it is the hardest and rarest hardstone. Jade has subtle translucent colors and was used to represent purity, goodness and virtue. Being that it was such a strong stone it was valuable, it was considered indestructible or immortal and people would often be buried with their jade items.
