What is IGI Certification? A Complete Guide for Jewelry Buyers

Understanding IGI Certification

When buying diamond jewelry, authenticity and quality assurance are crucial. IGI Certification, issued by the International Gemological Institute (IGI), provides an independent, professional evaluation of a diamond’s quality, ensuring transparency and trust.

Why IGI Certification Matters

Authenticity Guarantee – Confirms that the diamond is natural or lab-grown.
Quality Assessment – Grades the diamond based on the 4Cs: Cut, Color, Clarity, and Carat Weight.
Transparency & Trust – Ensures buyers get exactly what they pay for.
Resale & Insurance Value – A certified diamond holds better resale and appraisal value.

What Does an IGI Certificate Include?

Each IGI-certified diamond comes with a detailed report that includes:
- Diamond Shape & Measurements – Exact proportions of the stone.
- Cut, Color, Clarity & Carat Weight – The key factors affecting the diamond’s quality.
- Fluorescence & Polish – Additional details on brilliance and surface finish.
- Symmetry & Proportions – Affects how well the diamond reflects light.
- Laser Inscription (if applicable) – Unique identification number engraved on the diamond’s girdle.
