if you're looking for jewelry with a lab-grown diamond, you'll likely encounter terms like igi and gia . But what exactly do these abbreviations mean ? And why is a certificate so important if you want to be assured of quality, authenticity, and value ? In this blog post, we'll explain it clearly .
what is igi and gia ?
igi (international gemological institute) and gia (gemological institute of america) are globally recognized independent laboratories that grade and certify diamonds . They inspect a diamond for the well-known 4 cs: carat, clarity, color, and cut, and record this assessment in an official report .
what does a diamond certificate say ?
a certificate contains, among other things:
- the carat weight (carat)
- the degree of clarity
- the color gradation (color)
- a unique registration number
- sometimes a laser-marked inscription on the stone itself
this certificate gives you, as a buyer, independent proof of what you are purchasing . And prevents you from overpaying for a lower quality diamond .
is a certificate also required for lab-grown diamonds ?
absolutely . Although lab-grown diamonds are created under controlled conditions, they vary greatly in quality . An igi or gia certificate makes this clear and comparable . Without a certificate, you can't make a fair comparison with other diamonds .
