Diamond Certification: Defined

A diamond certification is a document, report or findings you receive from a third-party laboratory, describing the stone in all of its characteristics. This most commonly come the GIA, IGI, AGS, EGL, HRD and GSI.

With each diamond you’re considering, you should review its certification, which is issued by the grading entity. This certification describes the different elements of the diamond, such as the width, length, clarity and colour.

The Rigorous Certification Process 

Every certified diamond has been scientifically and separately measured and evaluated for the 4Cs and other predetermined characteristics. Gemologists operating independently of diamond retailers, miners and dealers assign grades that are consistent, accurate and reliable to these certified diamonds.

So you are assured that their evaluations and grading are indeed unbiased. You can think of these reports as a novel written by your favourite author.

They’re proof supporting the value of your diamond.

However, these certificates or reports do vary among different laboratories. In fact, even the same laboratories provide reports that have varying levels of information, which could range from the basic to the finer details.

But typically, grading reports comprises a chart that details the diamond’s colour grade, weight, cuts and angles and inclusion levels and also the diamond’s line diagram from the top view and side view.

Additionally, diamond treatments such as pressure, heat, lasers and other techniques to improve colour and clarity are included in the report and should be disclosed to the potential buyer.

What to Watch for in a Diamond Certification

When shopping for custom engagement rings and you’ve finally set your eyes on a stunningly gorgeous diamond, here are a few things to watch for when review the stone’s certification.

  • Consistency is first and foremost. Instead of comparing the grades between different certifications, look instead for consistency within a single entity’s grading decision.
  • Diamond grading is still subjective. Despite the “science” behind grading diamonds, it is still subjective, and there is no central organisation that mathematically defines what an “SI1” clarity or a “G” colour looks like.
  • Consider price over the stone’s certification. Along with the certification, the price should also be heavily evaluated. The numbers on the price tag should definitely reflect the actual beauty, cut and quality of the diamond—both with the naked eye and the certificate.
  • Labs provide different results. Each lab is different. While one could be looser in grading colour, the other could be looser in rating the stone’s clarity. Know which laboratories are consistent and trustworthy to avoid buying a diamond worth less than what is indicated in its certificate.

Trusted Labs

Predominant trusted laboratories in the UK are the following:

  • GIA (Gemological Institute of America)
  • HRD
  • IGI (International Gemological Institute)
  • AGS (well-recognised in the US, but hardly available in the UK)
  • Gubelin
  • GRS
  • SSEF

Relatively, if possible, first look for GIA, then IGI or HRD certificates when purchasing diamond jewellery pieces.
