ABOUT OUR SPEAKERS
Speaker – Garry Holloway
Diamond Grading Report Integrity & Consumer Trust
Diamond grading reports, or “certs,” are designed to assess quality objectively. This talk explores the science behind grading, revealing its limitations—face-up colour grading, the impact of cut, and the need for clearer standards. To maintain trust, the industry must embrace a more honest, science-driven approach. Join us as we challenge outdated practices and reimagine the future of diamond grading.
