925 Sterling Silver Black diamond Cross 18" Necklace
Black Diamonds Are Tough. The toughness of black diamonds is more than any other diamond, its toughness is 10 on the Mohs scale. And its polycrystalline structure makes it more difficult to cut than any other colored diamonds.
Black diamonds don’t shine in the traditional sense. Black diamonds actually absorb light instead of reflecting it, meaning their beauty comes from their surface which is polished like marble.
There are three main theories of how black diamonds are formed. These include the theory that black diamonds are formed through a meteoric impact. Another theory is that black diamonds are formed through radiation. Scientists believe that they could be the result of spontaneous fission of uranium and thorium. The last theory is perhaps the most out of this world, quite literally. Some scientists believe that black diamonds were formed in outer space. They theorize that black diamonds were formed in hydrogen-rich interstellar space and came to Earth via an asteroid crash between 2-4 million years ago.
Black diamonds have only been found in Brazil and Central Africa. It’s important to note that these two lands were adjacent in prehistoric times. Coincidence? We think not…
Larger black diamonds are actually made up of millions of other smaller black crystals. Traditionally, diamonds are a single, solid stone, but black diamonds are bound together by internal inclusions that hold millions of smaller pieces together. This is known as a polycrystalline structure and it is what gives them their color and also the reason why spots can appear dark grey.
Black diamonds are considered either as a curse or a blessing, depending on where you are. In ancient Indian culture, black diamonds were considered cursed because they resemble the color of a spider or snake’s eyes. However, in Italian culture black diamonds can be seen as a sign of reconciliation. Italians believe that touching a black stone would bring them good fortune in their marriage and would help pass any martial issues.
