Diamonds are often associated with brilliance and clarity, but there are other types that capture everyone's attention - eccentric black diamonds. These fascinating gems often raise questions about their authenticity and origin. In this article, we will explore the world of black diamonds, revealing the mysteries behind them and providing reasons why they should be part of your jewelry collection.
What is a black diamond?
Also known as "carbonado", black diamond is a form of polycrystalline diamond made up of hydrogen, graphite and carbon. According to the International Gem Society, it would have been formed 2.6 - 3.8 billion years ago, thanks to the explosion of a supernova. Researchers Stephen Haggerty and Jozsef Garai claim that the explosion, which took place outside our solar system, resulted in stellar dust. It would have condensed into asteroids that hit Earth.
Unlike classic diamonds, which are mined, black diamonds are only found in alluvial deposits in Brazil and the Central African Republic. Moreover, because the black diamond has hydrogen in its composition, a gas found in large quantities in the composition of stars, it strengthens the theory of the two scientists. Therefore, we can say that it originates in outer space.
Are black diamonds real?
As we have shown above, black diamonds are real. However, there is often confusion about their authenticity due to their unique and rare appearance. The truth is that these rare gemstones are natural, but there are also synthetic and treated versions on the market.
Natural black diamonds
Both colorless and natural black diamonds have the same structure and chemical characteristics. The color of the natural black diamond is mainly due to microscopic particles of hematite, carbon graphite and magnetite that penetrate deep inside the gemstone. These are considered inclusions and are part of the structure of the diamond. In addition, they form a high concentration of "carboniferous clouds" that absorb light and give the stone that metallic appearance. Also, due to these inclusions, a "carbonado" is much more difficult to cut, finish and polish.
Treated black diamonds
Treated black diamonds are actually colorless diamonds that, through treatments such as irradiation and heat, become opaque. At first, many of them acquire a shade of gray, and through the procedure of high temperature - low pressure they reach the black color.
Synthetic black diamonds
Synthetic black diamonds are created in a laboratory and are essentially white crystals treated by high-pressure carbon processing techniques. Thus, they end up having a black color. These are more affordable than natural ones, but they don't have the same value.
Are black diamonds expensive?
In recent years, "carbonados" have become increasingly popular. As with colorless diamonds, the prices of black diamonds vary depending on their type (natural, treated or synthetic). While a natural black diamond can be worth over 2000 euros, a lab-created one can be found for as little as 200 euros. Of course, carats contribute to the price.
What do black diamonds symbolize?
Black diamonds are often associated with mystery, power and elegance. They can symbolize endurance and strength to overcome obstacles. They are also considered symbols of sophistication, luxury and a unique personality. If you want to surprise your loved one with a special gift, then black diamond jewelry will be an excellent choice.
