Colour of Diamond

Colors in diamond originate from lattice defects and impurities. (See for further explanation about this). Only atoms of nitrogen, boron and hydrogen can be introduced into diamond.

Nitrogen is responsible for the yellow and brown \ orange shades in diamonds.

Boron is responsible for the gray blue colors. ranging from deep blue to sky blue.

Natural radiation over millions of years that causes the color in green diamond.

Extreme  pressure  deep in the earth can abnormally compress diamond’s  structure and creating a very rare of brown, purple, pink, or red diamonds. Evidence of it  can be seen in many Argyle pink and congac diamonds.
