Let’s talk diamonds…..Certificates


So as part of my diamond-buying series, I want to touch on a rather important topic: diamond certificates. If you have already visited any jewellery shops, you may have seen the words ‘certificated’, GIA, HRD, EGL and a lot more other acronyms. What does it all mean?

Basically, a diamond certificate is a report which has been done by an independent gem laboratory which tells you that:

a. The gem is actually a diamond

b. The quality of such diamond

Obviously, it is always wise to have a certificate mainly for point A but point b determines price, so it is just as important.

Unless you have a background in diamonds and know quality when you see it, I will always suggest to buy certificated diamonds. It gives you peace of mind.

Would any certificate do?

The answer is no. You want an independent certificate, not one provided by a jeweler. A certificate acts as an independent appraisal, so if the jeweler provides you with his/her own one, then it can be anything he/she wants it to be! There are three reputable certificates, and I will strongly suggest to keep it to these three:

  1. GIA (Gemological Institute of America)
  2. HRD (based in Antwerp)
  3. IGI (International Gemological Institute)

The above labs also offer some of the most informative and apprehensive websites when it comes to diamonds, so I recommend you pay them a small visit.

What about EGL?

EGL is one of the newest labs around, but one to avoid. They are basically unreliable and will print reports overestimating the quality of the diamonds in exchange for some ‘additional money’. So you may think you are getting a deal on a superb diamond, but the report is basically not a true reflection and are actually paying more than you should.

What else should I know?

A last point I would like to mention is that if you can, buy a diamond which is laser inscribed. This means that the diamond itself has a serial number etched on the girdle which  matches the certificate. This is the easiest way to know that the actually certificate matches the diamond in your possession. I will say that diamonds over 1.70ct tend to not be certified then as it is a much bigger size, it is much easier to identify.


Next post I will finally touch on the four C’s and the best combo depending on the size and cut of the diamond.
