It's written history goes back almost 3,500 years, and the history told by it's artifacts and artwork goes back much farther. Jade is a general term used to describe either jadeite or nephrite, known as true jade. It's composed of several minerals. It's smooth and rich in texture, but it's also extremely tough. It can be off-white, or dark green, and sometimes has a reddish tint.
Authentic jade is cool and never translucent.
It's edges seem sharp but do not cut- like justice. It hangs down to the ground- like humility. When struckm, it gives clear, ringing sounds- like music. The strains in it are not hidden and add to it's beauty- like truthfulness. It has brightness- like heaven.
