Causes of Colour: While there many factors to what causes colour, there are the same factors – chemistry and structure. When the chemical composition and crystal structure are close to perfect and pure the diamond will be completely colourless. However, when a diamonds chemical composition and crystal structure incorporate other atoms from surrounding elements the diamonds crystal becomes coloured.

When pressures increase around the diamond, this causes slight distortions within the diamond which can create colours like brown, red and pink. When there is natural radiation around a diamond with this increase of pressure will cause a green diamond. But when the pressure is normal for a diamond to grow and you add nitrogen atoms to the diamond structure you get a yellow diamond. The same holds true with adding boron in the same type of conditions, but instead of a yellow tint, you get a blue tint.
