What Is an IGI Certificate?
Everything You Need to KnowAbout Diamond Certification
The IGI Certificate is an internationally recognized document that verifies the authenticity and quality of a diamond. It is issued by the International Gemological Institute (IGI) – one of the world’s most respected and trusted gemological laboratories. At Labgrownlove, each certified diamond – whether lab-grown or natural comes with an IGI certificate for full transparency and peace of mind.

What exactly does the IGI certificate confirm?
The IGI certificate analyses and documents the quality of a diamond based on the famous 4 Cs:
• Carat – Weight
• Cut – Quality of cut
• Clarity – Purity
• Color – Color grade
Additionally, fluorescence, polish and symmetry are often evaluated.
Why is an IGI certificate important?
A certified diamond offers you the following advantages:
• Objective evaluation by independent experts
• International comparability
• Higher resale value
• Transparency when purchasing – you know exactly what you are getting
• Protection against counterfeiting thanks to laser engraving of the certificate number



Does the certificate also apply to lab-grown diamonds?
Yes. IGI is one of the leading institutes that also certifies lab-grown diamonds. These are tested with the same care and precision as natural diamonds. You therefore receive the same level of assurance – regardless of the stone's origin.

How do I know if my stone is IGI certified?
• You will receive a printed certificate with all the details of your diamond.
• The certificate number is usually microscopically lasered into the diamond's girdle.
• You can verify the certificate at any time on the official IGI website (www.igi.org).
Is IGI a Trustworthy Institute?
Absolutely- The International Gemological Institute, founded in Antwerp in 1975, is one of the most respected labs in the diamond industry. Alongside GIA and HRD, IGI is considered a top-tier authority – especially in the engagement ring and lab-grown diamond sectors.
Conclusion:
The IGI Certificate ensures that the quality of your diamond is transparent, verifiable, and internationally recognized.
It’s a seal of trust – whether you're buying a ring for yourself, a loved one, or as a lasting investment.
