| Industry Role | The most widely accepted and authoritative grading standard for Moissanite globally, utilizing the 4C framework to provide precise scientific analysis. |
The world's premier authority and pioneer for natural diamonds. Most high-value natural diamonds are certified by the GIA. |
| Aurae's Choice | We align with international standards, providing official GRA certificates for all stones 0.5ct and above. | GIA focuses heavily on premium natural diamonds and does not typically issue commercial certificates for Moissanite. |
*In short: Look for GIA when buying natural diamonds; look for GRA as the ultimate credential when investing in
premium Moissanite.*
