IGI Certification Guide
A diamond certificate gives you confidence in what you are buying. It confirms important details about the diamond, including carat weight, colour, clarity, measurements and origin.
For Lab-Grown diamonds, IGI certification is widely used and helps customers understand quality before choosing an engagement ring or fine jewellery piece.
What Is IGI?
IGI stands for International Gemological Institute. It is a diamond grading organisation that provides grading reports for both mined and Lab-Grown diamonds.
An IGI report helps identify and describe the diamond’s important characteristics.
| Report Detail | Meaning | Why It Matters |
|---|---|---|
| Carat | Diamond weight | Affects size and price |
| Colour | Colour grade | Affects brightness |
| Clarity | Inclusion grade | Affects clean appearance |
| Measurements | Diamond dimensions | Affects face-up look |
| Origin | Lab-Grown identification | Confirms diamond type |
Why Certification Matters
Certification removes guesswork. Instead of relying only on product images or descriptions, you can review the diamond’s grading information.
This is especially important for engagement rings and larger diamond jewellery purchases.
What Is Included in an IGI Report?
An IGI report usually includes carat weight, colour grade, clarity grade, measurements, polish, symmetry and other identifying details.
For Lab-Grown diamonds, the report also states that the diamond is laboratory-grown.
IGI and Lab-Grown Diamonds
IGI is widely used for Lab-Grown diamond grading because it provides clear reporting and recognises laboratory-grown origin.
Pear Jewels offers IGI certified Lab-Grown diamonds whenever applicable.
How to Read a Certificate
Start with the 4Cs, then review measurements, polish and symmetry. Use the certificate alongside product photos, setting details and your preferred style.
A certificate is important, but the finished jewellery design and craftsmanship also matter.
