HRD Antwerp Ends Loose Lab-Grown Diamond Certification
In a bold industry shift, HRD Antwerp, one of the world’s leading diamond grading labs, has announced it will stop certifying loose lab-grown diamonds (LGDs) starting end of 2026. This move positions HRD as the first major gem lab globally to make a full exit from grading loose synthetics.
The decision comes amid rising global sales of LGDs and increasing pressure to clearly distinguish them from natural diamonds.
What Will Change After 2026?
- No certification for loose lab-grown diamonds intended for commercial sale.
- Jewellery with lab-grown diamonds will still be certifiable.
- Research-only analysis of synthetic diamonds will continue for academic and technical purposes.
By eliminating loose LGD certification, HRD aims to strengthen consumer trust and refocus its identity around natural diamonds.
Why Is HRD Antwerp Doing This?
According to HRD and various industry insiders:
- The goal is to reduce market confusion between natural and synthetic diamonds.
- The lab seeks to preserve the prestige and value of natural diamonds in the eyes of consumers.
- HRD wants to set a new global standard by being the first to draw a firm line between synthetic and mined stones.
This change also follows growing concerns about pricing transparency and resale value for LGDs.
HRD Antwerp’s decision to discontinue loose LGD certification marks a new chapter in the diamond industry. As synthetic stones grow in popularity, this bold move reinforces the differentiation between natural and lab-grown diamonds, helping preserve long-term trust and value.
For anyone in the jewellery trade, staying informed and adapting certification strategies is key. Whether you support or question the decision, one thing is clear—the diamond grading landscape is evolving.
