GRA Certification

What is GRA Certification?

The GRA (Gemological Research Association) certificate is an independent verification that confirms the authenticity and quality of your moissanite stone.

Each certified stone is evaluated for its key characteristics, ensuring it meets high standards of brilliance and clarity.

What Does the Certificate Include?

Every GRA certificate typically includes:

Unique certification number

Stone shape and size

Color grade (D)

Clarity (VVS1)

This information guarantees that your moissanite meets the specifications described.
