GIA CERTIFIED TYPE IIb FANCY BLUE DIAMOND

Scientists classify diamonds into two main “types” – type I and type II – based on the presence or absence of nitrogen which can replace carbon atoms in a diamonds atomic structure. Type II diamonds contain little if any nitrogen and they are subdivided into two groups (IIa and IIb) both of which are quite rare (reportedly less that 2% of ALL gem diamonds fall into the type II category)
