BRUISE:
A minor chip or concussion on the stone that may create root-like lines inside the diamond. The presence of a tiny bruise can make the difference between an IF and a VVS1 grade. Bruises are found in diamonds of VVS1 and lower clarity grades. Of course if your diamond has a higher clarity grade, the bruise may be impossible to see with the naked eye, and difficult even under 10X magnification.
