First of all, we can see the difference in weight, the diamonds that we ordinary people come into contact with are generally one carat and two carats, but this black diamond weighing 88 carats has been shipped from France to Shanghai, and will be exhibited at the 3rd China International Import Expo, which will be its first performance in China, and this super black diamond appeared at the 3rd China International Import Expo, this diamond is called "one of the five largest black diamonds in the world".
This black diamond weighs 88 carats, has a diameter equivalent to a dollar coin, has 57 facets, and is worth about 100 million yuan。This black diamond will be promoted in Shanghai, the black diamond was originally owned by the European aristocracy in the Middle Ages, and later the French Karloff family named it "Kolloff Noir" after the aristocratic surname, kept in the basement of Karloff Jewelry *** in Paris, France, and rarely displayed in public.
What makes black diamonds unique in their intense black color is that the graphite and hematite they contain completely absorb light。Data shows that white and colored diamonds can be formed back 1 billion years ago, while black diamonds can be formed back 4 billion years, and research suggests that black diamonds may have been formed directly from interstellar clouds rich in carbon and hydrogen fragments that fell on Earth after planets** and became supernovae.
In recent years, young Chinese have increasingly gravitated towards diamonds。According to the data of the Quasi-Industry Association, as the millennial generation has become more and more influential on diamond culture, China's diamond consumption is no longer limited to the wedding scene, and diamond jewelry has gradually appeared in daily wear occasions, so since 2018, the growth rate of diamond consumption in China has gradually recovered to more than 4, and in 2019, China's diamond consumption was about 128.9 billion yuan, a year-on-year increase.

Compared with ordinary diamonds, the rarity, ** and purity of the material are significantly higher. The black diamond weighs 88 grams, has a diameter equivalent to a dollar coin, has 57 facets, and is worth about 100 million yuan. And the reason why black diamonds are unique is that the graphite and hematite contained in them completely absorb light, and they are made of the fragments of the planet's ** immortality.
-
The first is the luster, which can be seen in the case of a comparison between the two at the same time, the color of the black diamond is better, and the second is **, the former has very little reserves, so ** is higher.

Summary. Carbonado, commonly known as "black diamond," is the hardest form of natural diamond. It is an impure form of polycrystalline diamond composed of diamond, graphite and amorphous carbon, usually a porous aggregate of fine-grained diamond.
Through lead isotope analysis, carbonado is believed to be the product of carbon crystallization about 3 billion years ago. Isotopic studies have revealed further clues to the genesis of carbonado.
Do you know about black diamonds?
My question to you, it takes a little time to type, please be patient.
Carbonado, commonly known as "black diamond," is the hardest form of natural diamond. It is an impure form of polycrystalline diamond composed of diamond, graphite and amorphous carbon, usually a porous aggregate of fine-grained diamond. The most typical carbonado is found only in the Central African Republic and Brazil, where neither of these places is associated with kimberlite, the typical gemstone of diamonds.
Through lead isotope analysis, carbonado is believed to be the product of carbon crystallization about 3 billion years ago. Isotopic studies have revealed further clues to the genesis of carbonado.
Carbonado is also found in younger sedimentary beds. Because it contains graphite or other mixed materials, it is light gray and black and opaque, and has high hardness and firmness. Density.
Specific gravity. It usually exists in the form of round fragments or irregularities, and is mostly used in industry. With the continuous progress and development of the times, carbonado has also been used in the field of jewelry. [1]

And recent studies have shown that black diamonds may be directly formed by interstellar clouds rich in carbon and hydrogen, and the debris of planets** falling on Earth after becoming supernovae. People love the beautiful appearance of diamonds, but they also love the meaning it represents, it symbolizes eternal love and gives people beautiful expectations.
