Sphene, the yellow-green natural gemstone
Do you know the existence of the black diamond?
If you are used to thinking of diamonds as something colorless and crystalline, know that you are very wrong because there is not only that!
Diamond is a naturally occurring mineral in many more shades of color than you can imagine. In fact, they exist in various fancy colors and are called Fancy Diamonds:
- yellow diamonds
- red and pink diamonds
- green diamonds
- blue diamonds
- black diamonds
- brown diamonds. Together with blacks they are of lower value but very fashionable.
The history of the black diamond
The history of black diamonds has always been full of charm. It is said that black diamonds did not form on earth like all other minerals, but came from space, probably through an asteroid that would have hit the earth millions of years ago.
In fact, black diamond deposits, unlike white diamonds found in volcanic rock, have been found in deposits of alluvial origin located in Brazil and central Africa.
Furthermore, the black diamond is composed of iron oxides and graphite, and a type of carbon different from that of classic white diamonds.
Features of the black diamond
Black diamonds are truly rare and fascinating gems. They are not sparkling like other diamonds but it is their depth that contains something truly mysterious and elegant. True refined luxury that doesn’t want to appear.
Black diamonds having a translucent / opaque structure, are not evaluated according to the 4 C of the clasical diamonds (Color, Cut, Carat, Clarity). Indeed, any transparency in certain areas can be considered a defect. They are also very difficult to cut and work on. This is because they are very hard but definitely more porous than classic diamonds, i.e. with possible structural fragility. Most are heat treated, at very high temperatures, to make them obtain a uniform color.
Black diamonds have been used in jewelry for relatively few years.
Given their particular color they are also very popular in men’s jewelry.
Both as men’s rings and as men’s bracelets, such as the classic black diamonds tennis.
