The author of Collecting and Classifying Coloured
Diamonds, gemologist Steven Hofer states, black diamonds are in
"a transitional carbon state between graphite and pure
diamond". Hoffer continues, "The typical black diamond
is composed of a mishmash of atoms rather than a regular, homogenous
arrangement."
Black diamonds are both difficult and time consuming to cut.
Surfacing pitting and areas with varying degrees of transparency
are common problems.
