Features
As you
examine diamonds under magnification, you'll probably wonder
what you are looking at. Listed below are some of the clarity
features you'll see. Keep in mind that mother nature rarely
repeats herself; you may find variations and combinations
of these typical features.
Cracks
of various sizes are commonly seen in diamonds. If the cracks
are small, normally you need not worry about them. The crack
in figure 6.8 does not weaken the 'n-power loupe. diamond
and is not visible from a face-up position, so this stone
still received a very high focus. If you're grade of VSZ (very
slightly included) from the GIA.
You
should however be concerned about is or 25-50 mm. big cracks
like the one in figure 6.2. When cracks are jagged, they're
called fractures. When he greater your they're straight and
flat, they're called cleavages. Both types of cracks are often
called feathers due to the close resemblance.
Crystals
of all sorts of interesting shapes and sizes are also common
in diamonds help prevent Over 24 different minerals have been
identified as crystal inclusions in diamond, but the most
frequent type crystal seen is another diamond. Crystals can
lower the clarity grade of your diamond, but they can also
turn it into a collector's item.

spots are usually just crystals and cracks. If they look like
tiny dots, they are called pinpoints. Sometimes you may hear
black spots referred to as carbon spots, but this can mislead
people into believing that coal particles are in their diamonds.
Eric
Bruton discusses this on page 385 of his book Diamonds and
says, "Dark inclusions in diamond were for generations
called carbon spots, although it is now known that amorphous
carbon does not occur as inclusions." More often than
not, spots that look black are actually transparent.
