What Is Black Diamond?
Black Diamonds have become THE diamonds for current diamond jewellery, surpassing all coloured diamond categories. The theories of Black Diamond formation have much to do with that, especially since they have been linked to supernovas. A team of U.S. geologists have published evidence relating to a different origin of these black diamonds: interstellar space. They have found that black diamonds contain trace elements of nitrogen and hydrogen,?? which they claim, are sure indicators of an extra-terrestrial origin. The researchers found that the chemical properties of carbonado indicated that the mineral formed in a supernova explosion that took place prior to the formation of our Solar System. In this sense, carbonado are theorised to be akin to carbon-rich cosmic dust, likely having formed in an environment near carbon stars. The diamonds were eventually incorporated into solid bodies that subsequently fell to Earth as meteorites. Carbonado appears only in the Central African Republic and Brazil, in areas that are far from other diamond deposits. Carbonado, commonly known as the "Black Diamond", is the toughest form of natural diamond. It is an impure form of polycrystalline diamond consisting of diamond, graphite and amorphous carbon. It is found in alluvial deposits in the Central African Republic and mainly in Brazil. Its natural colour is black or dark grey, and it is more porous than other diamonds.
Natural black diamond is usually treated to obtain uniform colour. It is typically much better quality than completely natural untreated black diamond due to the nature of its inclusions. Enhanced black diamonds are stunning when set with contrasting white diamonds. To receive a black diamond is to receive a genuine diamond. The classy appearance of the black diamond has led to its growing popularity. It is an elegant gem with a rich look!
Black diamonds are called Fancy Black with a notation of natural colour. Black diamonds are not graded for "clarity" as you measure clarity on the light that passes through the gemstone and as such black diamonds are not rated the same way as other diamonds, for example, GIA does not grade black diamonds as they fall outside of its normal clarity range.
About a decade ago black diamonds were cheap, because most collectors and researchers weren’t interested in them. Recently prices have risen sharply. Today black diamonds are sold for prices that are comparable to those of white diamonds.
