10. The third C is Clarity
An inclusion is a flaw inside a diamond.
It could be a tiny crack or a crystal of
foreign material that creates the
inclusion.
The clarity of a diamond is influenced in
different ways by the number, size,
colour, location orientation and visibility
of inclusions.

11. The final C is Cut.
The cut relates to the way a diamond has
been shaped and polished from a rough
stone to the final gem.
The shape of a diamond and the quality of
workmanship are both described by the
cut.
Variations of cuts, such as the emerald,
round or pear shapes are used for
different kinds of jewelry.
