Black Diamond Gemstones

Black Diamonds are among the world's rarest diamonds. They are also Carbonado Diamonds. The diamonds are not really black but contains dark inclusions or impurities that result in the black look of the gem. It is believed that these stones were formed in the centre of the earth about 3.5 billion years ago and were brought into the surface because of volcanic eruptions. Black diamonds get their color from the presence of minerals like magnetite and Hematite.
