GIA certification: Definition and role

The GIA (Gemological Institute of America) is the leading organization for diamond evaluation and certification. It was founded in 1931 and sets international standards for the evaluation of precious stones.

A GIA certified diamond is analyzed according to rigorous scientific criteria, guaranteeing its authenticity and quality.

The 4Cs of GIA: A Global Evaluation Standard

1. Carat: The weight of the diamond

Carat is the unit of measurement for the weight of a diamond. A heavier diamond is generally more valuable, but other criteria influence its value.

2. Color: From D to Z

Diamonds are graded by hue, ranging from D (colorless) to Z (yellow or brownish hue). The more colorless the stone, the more valuable it is.

3. Clarity: Purity of the diamond

Natural imperfections (inclusions) influence the transparency of the diamond. The GIA grades clarity from FL (perfect) to I3 (visible inclusions).

4. Cut: Impact on shine

A perfect cut maximizes the diamond's brilliance by reflecting light optimally.
