Introduction of diamond

Diamond is a crystal of carbon under high temperature and high pressure and is the hardest mineral in nature. Its name comes from the Greek word "Adamas", which means hard and invincible.
Diamond is a rare, precious non-metallic mineral, plays an important role in the national economy. Diamonds are divided into two categories according to their use: high-quality granules can be used as jewel -grade diamonds for decorative objects, and fine-grain granules are used for industrial industrial diamonds.
Gem-grade diamond, also known as diamond, is brilliant and crystal clear. It is known as the “king of gems” and is of high value. It is recognized as the first commodity in the world. Its possession and consumption level are often regarded as a measure of individual and national economy. The sign of wealth. It can't reach gem-quality diamond (industrial diamond), and its superhardness is widely used in industrial fields such as electromechanical, optical, construction, transportation, metallurgy, geological exploration, national defense and modern high and new technology fields.
Diamond can be divided into two types, type I diamond and type II diamond. Type I diamonds are mostly common diamonds. Type II diamond is relatively rare, accounting for only 1% to 2% of the total diamond. Type II diamonds are often used in space technology and cutting-edge industries because of their good thermal conductivity, cleavage and semi-conductivity. The high-quality large-grain type II diamond with a slight blue color is regarded as a treasure in the diamond. For example, the world famous "Cullinan" diamond weighing 3106ct (Carat, Carat) belongs to this category.
Humans have a long history of understanding and developing diamonds. Diamonds were discovered in ancient India as early as the 3rd century BC. Since the beginning of the Year of the Christianity, diamonds have always been a symbol of wealth, power and status of the country and the royal family and the nobles.
The world's diamond mineral resources are not abundant. In 1996, the world's proven diamond reserves were only 1.9 billion ct, which is far from meeting the needs of gemstones and industrial consumption. Since the 1960s, synthetic diamond technology has emerged, and by the 1990s, synthetic diamonds have almost completely replaced industrial natural diamonds, accounting for more than 90% of the world's industrial diamond consumption (more than 99% in China). ). The main diamond producers are Australia, Russia, South Africa, Botswana and Zaire. The distribution of world diamonds is mainly controlled by the De Beers Central Sales Organization.
China discovered diamonds about 200 to 300 years ago. In the Ming and Qing Dynasties (about the 17th century), farmers in Hunan Province found diamonds in river sand. The geological exploration of diamonds began in the 1950s. So far, there are 6 famous diamonds found in China with a weight greater than 90ct, such as "Changlin Diamond" weighing about 158ct.
China's diamond mineral resources are relatively scarce. Through nearly 50 years of geological work, reserves have been identified only in Liaoning, Shandong, Hunan and Jiangsu provinces. By the end of 1996, China had retained 20,897,800 ct of diamond reserves, which did not occupy an important position in the world. In terms of quality, China's Liaoning Province produces diamonds with excellent texture, and gem-quality diamonds account for about 70% of total production. Since the 1990s, China's annual output of diamonds is about 10 to 150,000 ct, which is far from meeting the needs of domestic consumption. More than 99% of the industrial diamonds required by the country depend on domestically produced synthetic diamonds. In 1997, China's synthetic diamond production reached 440 million ct, and natural industrial diamonds accounted for a very limited proportion of consumption.
