This diamond is graded Type IIa based on the inclusions it carries, on grounds of being free of nitrogen. This places it in a category accounting to 1-2% of the naturally occurring diamonds in the world. Type IIa stones usually have perfect crystal shape, making them absolutely colorless. Some do exist which carry plastic distortion in the crystal, and consequent color emanating from the stone. These are the ones with fancy colors such as pink, purple, red, and brown. The deformed parts take in different wavelengths of the incident visible light.
