Main Functions
Permanent Marking:
Girl Number (GIA Number): This is the core application of a diamond's girdle, engraved with the certificate number from an internationally recognized certification organization (such as GIA, IGI, or HRD). This number corresponds to the certificate and serves as the diamond's identity, ensuring anti-counterfeiting and traceability.
Brand Logo/Trademark: Diamond brands or jewelers can engrave their own logo for brand promotion and anti-counterfeiting purposes.
Special Symbols/Patterns: Customized designs such as hearts and zodiac signs can be engraved to meet customized needs.
Anti-Counterfeiting and Traceability: The girdle number is the most important factor consumers use to verify the authenticity and quality of a diamond, significantly enhancing market transparency and consumer confidence.
