Chocolate is one name used to describe brown diamonds, the most common colour of diamond found.
From its Wikipedia entry for natural brown diamonds:
"Whereas the brown color due to irradiation or nickel impurity can be easily recognized through spectroscopic (e.g. absorption) measurements, the majority of natural brown diamonds do not show any characteristic absorption peaks. Whereas the consensus has been reached that the color relates to the plastic deformation, the particular reason has been reliably identified (large clusters of vacancies) only in type IIa natural brown diamond."
It depends on what you mean by mineral. A mineral is a 'wide range' term. The only one I know of is Alexandrite, but that is a color-changing mineral, not exactly blue all of the time.
Brown diamonds are the most common colour of gem-quality diamonds found.According to its Wikipedia page:"Several causes have been identified, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the latter are considered as the predominant cause, especially in pure diamonds."
Mother Nature makes diamonds from carbon using intense high pressure and extreme heat deep within the earth's mantle.
Boron is the trace element in blue diamonds.
Diamonds are formed by tremendous pressure under the earth's surface which causes carbon to crystallize. When this happens in the presence of certain trace elements, a distortion of the normal crystallization process can occur and result in the beautiful colors seen in some rare and expensive diamonds.
Diamonds are formed from carbon. Gem-quality diamonds include only this mineral, with the exception of some trace minerals, which can give a diamond colour.

A diamond is absolutely beautiful, even when in the raw. It is a native Element, and the Element that makes up a mineral diamond is carbon.
It's just the mineral's natural color.
White diamonds are valued on there color. The nearer a white diamond is to colorless the rarer it becomes. This raises the diamonds value. Imperfections in white diamonds lead to discoloring and can greatly reduce the value.

Diamond is the hardest mineral on earth. So using it as a tool means it can cut anything.
A rock drill may be tipped with industrial diamonds, because the diamond tip makes the drill harder than the rock(s). Diamond is the hardest natural mineral on Earth.
Mother earth makes black diamonds.
