Diamonds from Outer Space

This article technically isn't about mars, but I thought it was interesting anyway. Geologists have discovered that black diamonds are actually from outer space. Unlike conventional diamonds, the presence of hydrogen in black diamonds may indicate an orgin in the hydrogen-rich interstellar space. Black diamonds also can not be found in mining fields. Geologists believe that black diamonds were once the size of asteroids when they first landed on the earth. It was mentioned in class that earth and mars are constantly exchanging rocks. Essentially, black diamonds could be scattered throughout the solar system including Mars. Maybe diamond companies should be interested in colonizing Mars.
