Many countries have jade ware culture, but none of them has as long a history as China has. China's jade ware culture has undergone a long process of development from the New Stone Age 10,000 years ago to the present. 
Jade in China is varied and can be divided into two categories: hard and soft. Good materials provide strong basics for jade ware carving, but the value of a jade object depends on the skills and reputation of craftsmen, the dates of carving, peculiar modeling and the owner's status. Certainly, different people will have various views on the value of the same jade object.It is difficult to have a unanimous standard.Due to the highvalue of

ancient jade ware, there is an equally long tradition of fake jade ware, which looks much like the real thing. Jade ware collectors should be careful and seek the opinions of professionals before making any major purchases.
Value
The earth's crust contains over 1,000 kinds of stones, but only about a dozen belong to the jade family. Limited by undeveloped quarrying skills, ancient jade output was very small; therefore, the price of jade was high... The idea that someone may have been willing to give away 15 towns in exchange for a piece of jade reflects the great value the Chinese place on jade.
An old Chinese saying, "Gold has a price, but jade does not," so in traditional Chinese literature, gold and jade are often mentioned together and are seen as symbols of wealth. Even today the price of high quality jade is no less than a piece of gold of the same weight, and it has stepped down from its ancient sacred altar and has come into the lives of ordinary people.
