Black Diamond
Browse Black Diamond A black diamond, or carbonado, is much younger than other fancy colored diamonds. There
are two explanations for the origins of black diamonds. 3.5 billion years
ago, carbon atoms were squeezed into crystals in the infernally hot dense
mantel under the earth's surface. Through volcanic eruptions, black diamonds
reached the earth's surface between 100 million and 1.1 billion years
ago. Stephen Haggerty, geology professor at the University of Massachusetts,
believes that carbonados (which are almost exclusively found in Africa)
come from a meteorite."Billions of years ago distant exploding stars rich
in carbon produced dense clumps of diamonds from the shock waves and pressures,"
he writes.
Despite the fact that a black diamond is significantly more rare than
colorless diamonds, colorless diamonds have continue to be the mainstay
symbol for marital love. De Beers Consolidated Mines has largely been
in control of any available black diamond. They have created an interest
in the gem through controlling the price. Believing that the interest
in a black diamond is based on their rarity, they have merged with various
black diamond mines discoverers to continue diamond scarcity.
