What is GIA Certified Diamond: Everything Explained?
When we say a diamond is certified, it means that it has gone through a testing and grading process by an independent third-party lab and has a report which includes all the details about the diamond.
There are many reputable diamond grading laboratories in the world, such as the GIA, EGL, IGI, AGS, HRD, GSL, GSI, NGTC, etc.
Each of these labs has a distinct grading method and rating standards, as the diamond certification is subjective to labs.
However, amongst all, the Gemological Institute of America (GIA) is considered the most trustworthy lab in terms of its grading standards in the diamond & jewellery industry.
What does GIA certified diamond mean?
Actually, it is technically wrong to call it a GIA “certified” diamond because GIA only “grades” them. Even the document which has the result of the diamond assessment is called a report and not a certificate.
It has just become common practice to call it a GIA certified diamond but it is more like a misnomer.
So, being a GIA graded diamond means that the diamond has gone through a rigorous evaluation in a GIA lab and it has a report which contains all information
You must have heard about the iconic concept of diamond’s 4Cs (color, cut, clarity and carat). This standard of assessing a diamond was created by GIA.
Founded in 1931, GIA is an independent, non-profit organization that does R&D in the gem industry, defines and sets grading standards for diamond quality, and educates gem professionals.
GIA ensures that the diamond grading standards are fully objective; it keeps its all operations isolated from all the commercial trade, pricing, or valuation of diamonds.
