A diamond certificate is the key to evaluating the quality and authenticity of a diamond. The International Gemological Institute (IGI) offers detailed certificates, which are particularly important for laboratory panties. In this article we explain step by step how you read an IGI certificate and what you should pay attention to.

What is an IGI diamond certificate?

An IGI certificate is an independent evaluation report that documents the properties of a diamond. It contains information about:
- Karat weight (carat)
- Color (color)
- purity (Clarity)
- cut (cut)
- Dimensions and proportions
- fluorescence
- Polish and symmetry
- Laser engraving (if available)

This certificate serves as proof of quality and offers transparency when buying a diamond. At Stellini Diamonds we only sell diamonds with a certificate.
