Lab Grown Diamond Seminar – Recorded

This theoretical course provides a thorough overview of laboratory-grown diamonds (LGDs), covering all essential aspects to understand their role in today’s gem and jewelry industry.
Participants will study the main synthesis methods, including High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD), with a focus on the principles behind their formation and the typical features associated with each process.
The course also explores the LGD market, analyzing current trends, commercial positioning, consumer demand, and the ethical and economic factors that influence this growing segment.
In the identification module, students will learn how LGDs can be distinguished from natural diamonds through key visual features and gemological criteria, as well as the role of advanced detection techniques employed by laboratories.
Lastly, the course discusses the classification and grading of laboratory-grown diamonds, in line with international standards, and how gemological reports convey this information to the trade and the public.
This program is designed for professionals who seek a solid theoretical foundation in LGDs without hands-on training.
