New Identification Standards for Colored Diamonds
The International Gemological Institute (IGI) has announced a significant technological advancement in the screening of fancy-colored diamonds. As the price differential between natural and lab-grown colored stones remains substantial, the lab has expanded its 'D-check' screening method to specifically target colored varieties. This technology utilizes advanced photoluminescence to provide definitive identification, ensuring transparency for both retailers and consumers.
Key Developments:
- Enhanced Screening: The new method allows for rapid identification of lab-grown fancy-colored diamonds, which have seen a surge in market availability.
- Transparency Initiatives: IGI CFO Eashwar Iyer noted a 35-40% growth in the lab-grown sector, necessitating stricter verification to maintain consumer confidence.
- Global Calibration: The technology is being rolled out across all IGI worldwide locations to ensure standardized grading and disclosure.
