Gem-quality diamonds are coloured by the inclusion of trace minerals within the crystalline composition of the diamond.
For example, nitrogen makes diamonds yellow and/or brown; boron gives diamonds a blue hue, and some coloured diamonds acquire their colour based on structural defects.
One can find original colored diamonds to purchase from the 'Original Diamonds' website. They have diamonds listed in colors 'Exceptional White' and 'Rare White'.

Green diamonds are referred to as "green diamonds". They get their color from natural radiation exposure that causes defects in the diamond's crystal lattice, resulting in the green hue. They are one of the rarest colored diamonds in the world.
Natural black diamonds are rare. They are due to dark graphite inclusions. Their rarity makes them valuable. Most black diamonds are synthetic and made by heat treating low quality diamonds. The price of a synthetic black diamond is lower than that of white diamonds.
Nope. Black diamonds are very valuable (and very beautiful in my opinion!) but it's red colored diamonds that are considered the rarest and the most valuable.
