Diamond Certificates

Diamond Grading Report. This report comes
from the Gemological Institute of America
(GIA), and you should require this report
when you are purchasing a diamond.

With a diamond certificate, you can verify
the color, cut, carat, weight, and clarity of the
diamond. You don’t have to worry about a
diamond dealer telling you anything less than
the truth, because the certificate comes
from the GIA – not the dealer. You may be
required to pay for the certificate, but the
cost is usually low, and in many cases, it
will help you negotiate a better price on the
diamond – or keep you from purchasing a
lower quality diamond altogether.

If you buy a high quality diamond, and then
later decide to sell the diamond, you will
need to have the certificate, or you will have
a hard time selling it to someone else.
Furthermore, you can use the Diamond
Grading Report to look up the wholesale
value of the diamond in question. Use the
guide that is used by the diamond cutting

With the Certificate, or Diamond Grading
Report, there won’t be any doubts when you
are trying to purchase a diamond. You can
easily find out what the diamond is worth.
This will prevent you from overpaying, and it
can prevent a seller from under-charging as

A copy of the Diamond Grading Report
should be given to your insurance company
as well, when you insure the diamond. This
provides absolute, unquestionable proof of
the value of the diamond should it be stolen
in the future. Insurance companies cannot
argue with the report.

Avoid diamond dealers who seem reluctant
to provide a certificate! Also avoid sellers
who tell you that a certificate diamond will
cost you more – the only additional cost
should be the cost of the certificate, which
is low. If the dealer doesn’t want to provide
a certificate, then you don’t want to do
business with that dealer.

Don’t accept certificates from Gemological
Laboratories other than GIA. There are many
fly-by-night Gemological labs these days, but
in the end, GIA has been established as the
most respectable and trustworthy – not to
mention oldest – of the lot. So avoid dealers
who don’t want to use GIA for certification
purposes as well.

Don’t buy an expensive diamond without
paying the extra cost of the certificate. If a
dealer tries to convince you to make the
purchase without the certificate, or if they
want to use a company other than GIA, you
can be sure that the dealer has probably
greatly inflated the price of the diamond –
they have something that they are hiding
from you.
