Diamond Inclusion Photos: Piqué Carbon Inclusions






Internal Carbon Pique Diamond Inclusion Photography

Piqué are tiny black spots caused by undigested carbon inclusions (natts) within diamonds. Black or dark material found within a diamond's internal fracture planes can also be particles or crystallographic inclusions of graphite, ferropericlase, pyrrhotite and pentlandite.

Carbon piqué inclusions are sometimes removed by diamond enhancements such as laser drilling, which can leave their own types of unique inclusions.
