Diamond is commonly known as "diamond". It is also the original body of what we often call diamond, which is a mineral composed of carbon elements, a particle substance composed of elemental elements in nature, and a carbon allotrope (diamond, graphene, fullerene, carbon nanotubes, blue silk delite, etc.). Diamond is currently found on the earth in many natural existence in the hard material, at the same time diamond is not only produced on the earth, is found in the meteorite falling in the celestial body also has the formation of diamond phase. Diamond has a wide range of uses, such as cutting tools in crafts and industry. Graphite can form artificial diamond at high temperature and high pressure, and is also a precious stone. China also has the technology to make diamonds. It should be noted that the physical properties of graphite and diamond are completely different. Diamonds come in a variety of colors, from colorless to black, with colorless as the best. They can be transparent, translucent or opaque, or they can be nanodiamonds. Many diamonds have some yellow color, which is mainly due to impurities contained in the diamond. The refractive index of diamond is very high, and the dispersion property is also very strong, which is why the diamond reflects a colorful flash. Diamond fluoresces blue-green under X-ray irradiation. The primary diamond ore is only produced in kimberlite pipe or a few potassium-magnesium lamprophyre. Kimberlite is their mother rock, and diamonds in other places are transported by rivers, glaciers, and so on. Diamonds are generally in granular form. If the diamond is heated to 1000 ° C, it will slowly turn into graphite and carbon dioxide gas.

Carbonado is a naturally occurring polycrystalline diamond found in alluvial deposits in the Central African Republic and Brazil. Its natural color is black or dark gray, and it has more pores than other diamonds, and the finished black diamond has become one of the more popular ornaments in the upper class. Among the diamonds of various colors, black diamonds are particularly precious because of their scarcity. In contrast to the more gemological significance of black diamonds, carbonados generally refer to the natural production of black diamond rough stone. Its gem-quality individual is cut black diamond.

How Black Gold is formed: Black diamonds, also known as carbonados, have a black porous structure that is as hard as other diamonds and are found only in Brazil and the Central African Republic. Black diamonds are mostly in the form of irregular or round fragments, so they are more commonly used in industry. With the development of The Times, black diamonds are also used in the field of jewelry, and because of the rare quantity, the value is also quite expensive. According to the analysis, in January 2012, scientists confirmed that the black diamond is a supernova after the survival of the material to form a meteor, possibly up to 1 mile (about 1.6 kilometers) in diameter, through the Earth's atmosphere after being crushed into pieces, falling to South America and Africa to be buried in the ground after the formation. Black diamonds, also known as carbonados, have a black porous structure and are as hard as other diamonds and are found only in Brazil and the Central African Republic. From Australia to Siberia, from China to India, the process of forming ordinary diamonds is virtually the same, says astrophysicist Michael Hajilty of Florida State University. But the composition of these diamonds and black diamonds is not the same. Previous research has also been supported by new data showing that black diamonds are actually the product of supernova explosions, when they fall to Earth, they are about a kilometer or more in diameter, like a small planet.
