What is a black diamond?

Black diamond is formed from graphite, diamond, and amorphous carbon. It is polycrystalline and has a high density. It appears completely black due to the high number of inclusions it has.

They are also called carbonado, the Portuguese term for black diamond.

Are black diamonds similar to coloured diamonds?

No, they aren’t similar to coloured diamonds. A black diamond has more in common with a colourless diamond. The inclusions or black spots in a black diamond are small crystals of mineral carbon. But coloured diamonds are coloured from the chemical impurities present in them.

So, a black diamond contains millions of carbon crystals in them while a colourless diamond has a few of them.

Where are they found?

Most carbonados are found in alluvial deposits or riverbeds of Brazil, Central Africa, and Russia. Both Brazil and Central Africa were aligned together during ancient periods, and hence they are found in both places.

What is the history of Carbonados?

They were discovered in Brazil in 1840. During the initial days, it was considered unfit for jewellery making and more suitable for industrial use. The difficulty in cutting these diamonds was the major reason for this.

This popular misconception was blown into dust in 1996 when the founder of Swiss Watches started collecting men’s and women’s watches made of black diamonds.

Fast-forwarding to the present, these diamonds are gradually earning their place in the fashion industry, and even wedding rings made out of them are in demand.
