What Is Diamond Clarity?
The clarity of a diamond is perhaps one of its most valuable
selling points in the eye of the consumer. A diamond, that has
flash and fire, will stand out even above others that are far
larger.
That's because diamonds are basically prisms, which capture
light and reflect it back and forth, before it leaves the stone.
If you had two similar stones and were wondering which of them
was the diamond, you could put a tiny light behind each one and
see how the light passed through it. If you basically got the
beam of light coming out the other side, the stone is not
genuine. A diamond refracts the light so many times, that it
would only emerge from the other side as a soft glow.
Clarity is considered to be how "clean" the diamond is. Diamonds
can have minor inclusions, which are miniscule amounts of gas,
liquid, and even minerals, all of which cause an interruption in
the flow of light through a stone. Inclusions can be so small,
they go unseen by the naked eye. Others may not be visible,
especially in small stones, but if they are of the right type,
or there are several of them, their presence will disrupt the
passage of light to the point where the stone is dull, or looks
cloudy.
Some of the finest diamonds in the world have an inclusion of
one kind or another, but it does not detract from the overall
quality, when considered together with the cut, color and
carats.
