Diamond prices can be a bit confusing for the uninitiated. How does one
price a diamond? How do you know what the value of a diamond is? Here is
some information about diamond prices.
Diamonds are judged, valued or graded on the quality of certain
characteristics they have.
Firstly the Cut. All diamonds are originally rough and somewhat awkward in
shape. They need to be cut to a certain shape to produce the best possible
effect of sparkle and brilliance. The master cutter can take from a few
moments to anywhere up to weeks and months for a big diamond. The wrong cut
can reduce the value of a diamond considerably.
Then there is the color. Apart from specifically colored diamonds such as
the Rose or Blue diamonds (and even black, very rare I might add), most
diamonds are transparent. HOW transparent is the issue. The more transparent
the better as they let more light in and through the diamond. Not always
visible to the naked eye, some diamonds have coloring in them such as yellow
or brown, caused by mineral deposits in the diamonds when it was first made.
These reduce the diamond value as they also reduce the brilliance and can
actually make for a very dull diamond.
The Clarity plays an important part in the grading of a diamond. Virtually
all diamonds have imperfections, also called inclusions, and these are like
small blimps, mostly invisible to the naked eye, and they also affect the
light entering the stone. They can inhibit or deflect the light through the
sides and reduce the sparkle of the diamond. They can sometimes be seen as
black spots in the diamond. The number and size determines the grading of
clarity a diamond might have. Obviously the less inclusions there are the
better and more valuable the stone.
The carat weight is the other determining characteristic. All things being
equal with the other three characteristics, the value of a diamond increases
almost exponentially with the weight. A 2 carat diamond is going to be worth
about 4 times the value of a one carat diamond. This explains why a 30 carat
diamond can be priced in the millions even though it is only 30 times
heavier than a one carat diamond. Simply put the heavier the diamond is, the
more rare it is and this affects the value of a diamond also.
Each of the above characteristics can be graded on a chart and diamond
appraisers check these qualities against existing diamonds they hold for
this purpose and grade a diamond accordingly. This then gives an ideas of
the value and therefore the price of the diamond.
