Primary deposits are located on the north slope of the Tian Shan (or Tien Shan) Mountains. Most green jade production is from the Manasi River Valley in the south of Jungar Basin. Nephrite with a very obvious green hue is called вЂњgreen nephriteвЂќ (вЂњBi YuвЂќ in Chinese). Most of the production from these two areas is white, light greenish white, or light green. Traditionally named вЂњHetian JadeвЂќ is mainly from the Kunlun (Karakoram) and AвЂ™erjin (Altai) Mountains. The area is known for yielding the famous top-quality white вЂњmutton fatвЂќ jade. Hetian, also known as Hotan, is located in northwestern China (Xinjiang Uygur Autonomous Region) and has always been synonymous with the best nephrite. They are all major suppliers for the China market. The most economically important green nephrite sources are located in northwestern China, British Columbia, and Siberia.

The three most commercially important deposits-in China, British Columbia, and Siberia-all have similar geological environments. Major green nephrite deposits form within serpentinite belts along old or still-active subduction zones. Subduction and obduction occur during continental-oceanic collisions, so most ophiolite belts occur along old suture zones and current subduction zones. Since serpentinite belongs to ophiolite belts and ophiolite is of oceanic origin, itвЂ™s only transported to land by subduction or obduction. Its formation results from metasomatic reactions promoted by the presence of calcium-rich hydrous fluid along the contacts (Harlow et al., 2005).ДЄlthough deposits around the globe share a similar geological setting, there is no single formation model. Green nephrite occurs along the contacts between serpentinite units and more silicic (rich in silica) rocks such as granitic intrusive bodies, argillite, chert, or greywacke in obduction settings, where continental and oceanic crusts collide (Harlow at al., 2005). History, production, and trading policies, and the demand from China, combine to influence the modern green nephrite market. Since Chinese green nephrite production keeps shrinking, the main products on the market are from these two sources. Today, nephrite holds an exalted place in the Chinese market, motivating Canadian and Russian miners. While very few people question ChinaвЂ™s status as the largest nephrite jade market, the sourcing, manufacturing, and trading of the stone have never stopped evolving.

The вЂњBan ZhiвЂќ ring was once worn on a manвЂ™s thumb and designed with a very thick shank to protect the skin during archery practice. It was the first time that gem materials were used on Olympic medals and it reignited an awareness of, and love for, nephrite jade. To display their pride in jade culture, the Chinese mounted nephrite jade into the award medals used in the 2008 Beijing Olympic Games. Also used to fashion tools, jade is a part of every aspect of peopleвЂ™s lives. In China, jade symbolizes a connection between the living and the dead as well as power, wealth, and social class. The name jade had always applied to nephrite until jadeite jade was imported into China about 200 to 250 years ago. And nephriteвЂ™s history on other continents goes back 4,000 to 5,000 years. However, nephrite jade has been an important part of ChinaвЂ™s jade culture for more than 5,000 years. Record-setting prices for jadeite jade jewelry have been in the industry news spotlight for the past 30 years. Some even use the word to refer to all beautiful rocks, demonstrating the significance of jade in the Chinese culture. The Chinese character вЂњYuвЂќ is equivalent to the English term вЂњjade,вЂќ but the termвЂ™s meaning has broadened to include both nephrite and jadeite jade.

It was carved by Master Zhang Tiecheng to mimic the style of the stamp used by Emperor Qianlong, historically known as jadeвЂ™s biggest fan. ItвЂ™s made of a piece of top-quality light green nephrite weighing 4.28 kilograms (about 9 lbs.).

This is the official stamp of the 2010 Shanghai World Expo. TheyвЂ™re no longer in use, but today many of ChinaвЂ™s organizations use nephrite stamps to depict major events. Almost all were made of nephrite jade, chosen for its unequaled rarity, durability, and beauty.
