And Why It Matters More Than Ever
~By Auric Charms Editorial Team
"In today’s world of conscious luxury, buying a diamond isn't just about the sparkle, it's about trust. That trust begins with one powerful piece of paper: the IGI Certification. But what exactly is this certificate, and why is it essential when choosing a lab-grown diamond? Let’s decode this together."
What Is an IGI Certificate?
The International Gemological Institute (IGI) is a world-renowned gem lab, established in 1975, that specializes in grading both natural and lab-grown diamonds. An IGI certificate is an official report detailing the exact characteristics of your diamond: from the 4Cs (cut, color, clarity, and carat) to finish, polish, symmetry, and more.
It’s not just paperwork, it’s a diamond’s DNA.
Why Lab-Grown Diamonds Still Need Certification
Just because a diamond is made in a lab doesn’t mean it’s automatically flawless. Not all lab-grown diamonds are created equal, and a certificate ensures you're buying a genuine, top-tier stone, not a misleading or poorly cut gem.
IGI certification helps you:
Know the exact quality of your diamond
Ensure your diamond is ethically and transparently graded
Receive insurance coverage based on verified value
Increase resale or heirloom value
Avoid low-quality imitations or overpaying
What’s Included in an IGI Diamond Certificate?
Every IGI-certified lab-grown diamond comes with a comprehensive grading report. Here's what you'll find:
1. Carat Weight
Defines the actual weight of the diamond, measured in carats. A larger carat = higher value, but cut and proportion also impact sparkle.
2. Color Grade
Rated from D (colorless) to Z (light yellow or brown). Most Auric Charms diamonds fall between D-F, offering near-flawless whiteness.
3. Clarity Grade
Using 10x magnification, IGI gemologists look for inclusions or blemishes. Grades range from FL (Flawless) to I (Included).
4. Cut Grade
The most critical factor. Cut affects brilliance, fire, and scintillation. IGI evaluates symmetry, proportions, crown height, pavilion depth, and polish.
Diamond Proportions: Beyond the Basics
IGI goes even further, breaking down your diamond’s optical performance through detailed proportions:
Table %: Size of the diamond's top facet
Crown Height & Angle: Light reflection from the top
Pavilion Depth & Angle: Light return from the bottom
Girdle Thickness: The edge's thickness, affecting durability
Culet: The point at the bottom-preferably “None” for brilliance
All these dimensions affect how the diamond captures and reflects light, making
your ring truly shine.
IGI + Lab-Grown = Responsible Luxury
Lab-grown diamonds already offer major advantages:
Eco-friendly with a lower carbon footprint
Conflict-free, ethically created
Cost-effective, up to 40% less than mined diamonds
An IGI certificate elevates this further with independent verification, ensuring you're not just buying an ethical diamond, but a top-quality one.
