Diamonds are categorized into four types: Type Ia, Type Ib, Type IIa, and Type IIb. These types represent the level of impurities measured at the atomic level, within the crystal lattice of carbon atoms, and require an infrared spectrometer to detect them, unlike the more common inclusions which can be seen by the naked eye or a diamond loupe.

Diamond Type Classification.The foundation of the type classification system is the presence or absence of nitrogen, the most common impurity in diamond. Type I diamonds are defined as containing sufficient N to be measurable by IR absorption spectroscopy, whereas type II diamonds do not contain enough N to be detected by the IR spectrometer.
