DIAMOND PROGRAM 2025
BRAND NEW PROGRAM
In this 4-session online seminar with diamond stories in science, history and in the jewellery trade you’ll learn more about diamond that is probably the most popular precious stone from multiple angles of interest.
Discover diamond’s fascinating and long geological history that is behind its remarkable properties as a mineral that has been used by mankind for more that 2,000 years both as a tool and as a gemstone. Learn about the history of diamond mining, occurrences and diamond cuts and their impact in jewellery. Understand what are diamond grading systems, how diamond reports are read. Find out about the treatments that may modify the visual appearance of a diamond. Get an update on synthetic diamonds (aka laboratory-grown diamonds) and engage in a discussion on their current sales/marketing narratives.
The sessions were specially crafted to provide tools and product knowledge for sales associates in story telling but are also of interest to jewellery, antiques and gemmology student or professional looking for diamond-related info. This short-duration live format in an online room with limited seats is learning-friendly as it promotes engagement with the tutor and colleagues in a dynamic and relaxed environment.

As always, Rui’s gem classes are outstanding (and a lot of fun!) to attend. With his decade-long gem & jewellery knowledge and background, every aspect of the history of jewellery becomes a fascinating story you’d like to learn more about. I highly recommend his classes!

I have taken several informative educational webinar classes with Rui. Each section was well designed and covered the topic clearly and thoroughly. The presentations include excellent photos, graphs and a detailed bibliography. Even a seasoned gemologist will enjoy and learn from the classes because Rui puts the information in a historical context. Rui is very knowledgeable and passionate about gemology and I can highly recommend his classes.

The knowledge I acquired in Mr. Rui Galopim's workshop exceeded my expectations. Since I want to dedicate myself to 3D jewelry design, this workshop was very helpful to me in finding better design solutions. I found particularly interesting the part dedicated to the quotation of a diamond jewel. It allows me to make better choices in order to avoid unnecessary production costs. I am very excited with all the information. It was definitely the workshop I needed.

This past week, I had the pleasure of attending the Applied Gemmology for Jewellery Designers seminar, led by Rui Galopim de Carvalho, whom I have admired and followed for a long time. Rui has a remarkable talent for making his vast knowledge of jewellery, gemmology, and history, both accessible and captivating. From a jewellery designer's perspective, I found his course especially enriching. It provided a comprehensive overview of essential topics, enriched with fascinating anecdotes and invaluable advice. I will especially remember his emphasis on the importance of continuing education to assimilate concepts that should never fade with time and foremost, how he communicates his deep passion for the precious art of jewellery.

We all thoroughly enjoyed your class on Synthetic Diamonds. The information provided was at a level suitable for both beginners and more experienced gemmologists. It gave us lots to talk about at work the next day and motivation to read and learn more.
