- Red to pink diamonds – Scientists are still debating as to how diamonds achieve a pink to red color. Red diamonds are the rarest, with pink ones right behind them along with blue diamonds. However, experts believe that the color is due to the extreme pressure the diamond gets as it rises towards the earth’s surface.

- Orange diamonds – Orange diamonds belong in the range of yellow to brown diamonds and is also caused by the nitrogen concentration with the stone. However, pure orange diamonds are hard to come by.
- Green diamonds – Green diamonds are one of the most unique and beautiful colored diamonds. They achieve this through natural gamma radiation.
