Carbonado - A Black Diamond From Space. The rarest and hardest diamonds on earth come from outer space. Carbonados, dark and uncrystalized diamonds do not look like any other diamonds on earth because they were created by an exploding star before the formation of our solar system and delivered to Earth by an asteroid over two billion years ago. These rare diamonds are only found on the east coast of Brazil and the west coast of the Central African Republic which were joined together at the time of the meteorite impact over two billion years ago. Because of the lack of crystal structure there are no shear planes in which to facet these fascinating black diamonds. (the color can vary from black to dark grey and dark green depending on their trace elements). The proof of an extraterrestrial origin is the presence of nitrogen and hydrogen in their matrix. The presence of hydrogen in Carbonados indicates that an origin in a hydrogen-rich interstellar space and formed from a supernova explosion of a star several times larger than our sun. Carbonados are never found in any diamond mines anywhere else in the world which is consistent with their origin from a single asteroid impact over two billion years ago with all other traces of the meteorite long weathered away with only the few small black diamonds remaining.
Most Carbonado black diamonds recovered have been small weighing 3 carats or less. This large 22mm x 15mm, 24.38 carat lustrous charcoal grey stone is certainly the exception. It is completely original with a microscopic pebbly appearance of the individual diamond crystals being compressed together within the star during formation and is both beautiful and rare being older than any other rocks or diamonds found on earth (older than 4.56 billion years)
