If a diamond is classified as Type IIa, it indicates that the diamond contains almost none or is completely free of nitrogen. Since nitrogen is one of the reasons contributing to the yellow hue in diamonds, Type IIa represents utmost purity and makes up only 1-2% of all natural diamonds. Many of the world’s most famous diamonds are Type IIa, including the Cullinan and Kooh-i-Noor.
