Certification Guide

At Craftier, we prioritize transparency, quality, and trust. Each piece of jewelry we offer comes with certification from industry-leading gemological institutes to guarantee the authenticity and quality of your lab-grown diamonds.

Why Certification Matters

Certification confirms the 4Cs—cut, color, clarity, and carat—of a diamond. When you purchase a certified diamond, you’re receiving a stone that has been thoroughly evaluated by a trusted gemological institute, providing you with confidence in its quality and value.
