Pricing most products is quite easy.
Determine how much it costs to make the
item, how much it costs to market that item,
and then mark it up by 15 – 30% or more.
Simple, right? Well, pricing diamonds isn't
quite that simple. There are many factors
that are considered when diamonds are
priced.

Diamond prices are determined first by
adding the cost of the rough diamond, the
cost of cutting the diamond, and all other
costs necessary to turn the rough diamond
into a marketable diamond. Depending on
the importance of the diamond, an
independent company may be called in to
certify the grade of the diamond based on
color, cut, clarity, and weight.

At this point, the diamond becomes more
expensive each time it changes hands, until
it finally reaches a retailer, where the price is
raised a bit more. Before reaching the
retailer, however, the diamond must travel
from the mine, to the cutter and polisher, to
the independent grading company, and
then to the Primary market. Once it has
reached the primary market, it will be
purchased by diamond dealers and
wholesalers, and from there it will be sold
to retailers.

As you can see, the earlier you can purchase
a diamond in the process, the lower the cost
of the diamond will be – but not the value.
The value is based on what the diamond will
sell for in the market place – through a retailer.

If you own a diamond, and you have no idea
how much it is worth, you can have it
appraised, but the appraisal may not be
accurate. You will be better off obtaining a
certificate through GIA – Gemological Institute
of America. With the information on this
certificate, you can use a cutter's guide to
accurately determine what your diamond is
worth.

There are also many diamond price
calculators available. These can be found
on the Internet, and many diamond dealers
use these as well. You must realize, however,
that before you can accurately price a
diamond, without a Diamond Grade Report,
you need to know quite a bit about diamonds,
such as different cuts, clarity, color, and weight
– and how each of those aspects adds to the
value of a diamond, or decreases the value of
the diamond as the case may be.

Again, you will be better off if you get a
Diamond Grading Report on the diamond,
and use that information to look up the price
in one of the guides that the diamond cutting
industry uses. This will give you the most
accurate value of the diamond in your
possession, or of the diamond you are
considering purchasing.
