Diamond comes from the Greek Adamas, meaning indestructible.This is a fair name to give them, as they are the hardest known natural material on Mohs Scale of Mineral Hardness. The density is one of the reasons it is prized so much as a gemstone. Unlike many other jewels, it is suited to everyday wear and tear because of its resistance to scratching (because it can only be scratched by other diamonds) and it maintains its polish excellently.
De Beers, a company based in Johannesburg, South Africa and London, England, controls 40% of the worlds diamond trade. In an article from The Telegraph, De Beers stated that they are running out of diamonds. “In the last two decades the industry has found no new diamond deposit to match the two biggest mines in Africa, owned by De Beers, or the best Russian mines of Alrosa, the other big diamond producer.”
In some of the more politically unstable central and west African countries, revolutionary groups have taken control of diamonds mines, using the proceeds of the sales to back their own operations. Diamonds sold through this process are called blood diamonds.
