Speaking of ore, it must be diamond, which is the harder stone in the ore industry, such as fine grinding, high-hard cutting materials, drills and so on. Diamonds are also used in parts of many precision instruments. There are many colors of diamonds, from colorless, white and even black. Some are transparent, some are translucent or opaque. Most diamonds have a yellow tinge. High refractive index, dispersion performance is also very strong, so this is the reason why diamond can reflect colorful. Diamond fluoresces blue-green under X-ray irradiation. Diamonds are produced in kimberlite tubes. Kimberlite is their native rock, other diamonds are washed down by rivers, glaciers and so on. Diamond is granular. If the diamond is heated to 1,000 degrees, it will slowly turn into graphite.

In fact, diamond is what we call diamond, which is a kind of ore composed of pure carbon.

Around the 1950s, the United States used graphite as a raw material and created artificial diamond under high temperature and pressure. Synthetic diamonds have been widely used in production and life, and it is still difficult to create large diamonds with current technology.

Diamond in 1987 data, diamond mining areas in China are: Jinan mining area, West Luxi, Northern Jiangsu, northern Anhui mining area, Jin, Yu, Ji mining area, has been found in Taihang Mountain, Songshan Mountain, Wutai Mountain and other places kimberlite. Four diamond placers of industrial value have been found in the Yuanshui River basin of Hunan Province in Xiang, Qian, Hubei and Chuancheng mining areas.
