The crystals of diamond are in a lattice structure. All the diamonds which are formed naturally due to combination of carbon atoms are colorless. A diamond attains a color due to the type of impuirities it is being surrounded with at the time of formation. So a colorless diamond turns into a brown diamond when it is being surrounded by nickel impurities.
