Its natural color is black or dark gray, and diamonds with more pores than other diamonds have become one of the most popular ornaments in the upper class.　　　　The product of supernova explosion 　　　　 black diamond, also known as black diamond, has a black porous structure and has a hardness comparable to other diamonds. It only exists in Brazil and the Central African Republic. Florida State University astrophysicist Hajiti said that from Australia to Siberia, from China to India, the formation process of ordinary diamonds is actually the same. But the composition of these diamonds and black diamonds are different. Previous research results are also supported by the latest data. Black diamonds are actually the product of supernova explosions. When they first fell on the earth, their diameter was about one kilometer or more, just like a small planet. Scientists also found a large amount of hydrogen in black diamonds, indicating that it came from outer space rich in hydrogen. In other words, black diamonds may have already existed in the universe before the earth was born.　　　　Unusual properties　　　　Black diamonds have many tiny black crystals, usually pea-sized or larger aggregate polycrystals. The most unique thing is that black diamonds can only be found in the Central African Republic and Brazil, and a very small part are found in the Republic of South Africa, but not in the Kimberlite where diamonds are commonly found. The lead isotope analysis crystals formed about 300 million years ago in young sedimentary rocks. Black diamonds do not exist in the form of crystals, but in the form of irregular or round fragments. Opaque, no cleavage, density 3.012～3.416g/cm3. 10 Mohs hardness the same as other diamonds.　　　　Cleaning method　　　　 Use a small bowl or teacup to hold warm water. Dip the diamonds in water, scrub them gently with a toothbrush, put them in a mesh sieve, and rinse them with warm water under the tap.

Colored diamonds are very rare. Naturally formed diamonds with colored hues are labeled with the adjective 'rare'. The value of rare colored diamonds is determined by their color density. The difference in color is due to the different crystal molecular structure, or the different types and contents of impurities contained in them. If a diamond is black, it means that it is in the transitional stage between graphite and real diamonds, and it also belongs to the'rare' diamond series. In the entire diamond family. Black diamonds are usually the rarest. Sometimes people confuse black diamonds with colorless diamonds that contain black inclusions.
