Blue Diamond Types. Most pure blue diamonds are Type IIb, meaning they either very few or a complete lack of nitrogen impurities. Type Ia blue stones, on the other hand, which contain a secondary hue, get their color from the presence of hydrogen. The modifying color will be referred to in their gemological grading reports.
