What is GIA Certificate or Diamond Grading
A diamond certificate is also known as a 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
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.

|Reputed jewellers and diamond sellers will usually provide a diamond grading report,
often GIA Certificate, to verify diamond's true characteristics.
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 well.
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 diamond certificate! Also avoid sellers who tell you that
certified diamonds 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 diamond certificate, then you don’t want to do business with that
GIA Certificate is the
Don’t accept diamond certificate 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.
Here's the list of best known diamond certificates:
- GIA certificates - issued by Gemological Institute of America (non-profit org)
- IGI certificates - issued by International Gemological Institute, from Antwerp
- HRD certificates - issued by Diamond High Council (The Hoge Raad voor Diamant), from
- EGL certificates - issued by European Gemological Laboratory (for-profit org.)
Don’t buy an expensive diamond without paying the extra cost of the GIA certificate. If a dealer tries to
convince you to make the purchase without diamond 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.
