IDENTIFICATION
For a Diamond to be real, it must possess some inclusions. These
inclusions are visible by naked eye or under magnification. If no
inclusions, black spots or milk patches, are visible in a Diamond
then either it is a zirconia or piece of glass. Diamonds, which
do not have any inclusions under 50x magnification, are very rare
and can be found with collectors only.
The small black spots visible in Diamonds are crystals of Graphite
or other forms of 'Carbon'. These black spots shine under light.
Diamonds have an affinity for grease; the surface of a cut Diamond
will generally have a film of grease if it had been handled.
The most important test of a diamond is that, all light entering
the front of the stone is totally reflected from the back facets,
which form a series of mirrors. A well-cut diamond if viewed from
the back and held up to the light, will show only a pinpoint of
light from the culet.
In addition to this looking down on a brilliant-cut diamond one
cannot see the wearer's finger below the stone, as can be seen in
other stones. White light entering a diamond is dispersed into a
spectrum of colours, giving flasks of different colours from the
smaller crown facets.
