Session Title: Understanding Precious Corals 

Session Begins:  12:00pm (EDT) / 11:00am (CDT)

Precious corals have been used by mankind since pre-historic times and still hold an important status in many cultures and geographies. As a biogenic gem material that is collected in the wild, sustainability concerns have been raised and have been addressed by the jewelry industry notably by CIBJO, The World Jewelry Confederation, on its Coral Commission under the leadership of Enzo Liverino. The nomenclature and clarifications that will be covered in this talk are a result of the work of the Coral Commission over the past decade.

As a Portuguese national, Rui has a particular interest in Portuguese jewelry of cultural heritage and has recently studied the gemstones in the Portuguese crown jewels for the new royal treasury museum in Palácio Nacional da Ajuda.

Speaker:  Helen Molesworth 

Session Title:  The Gemstone Market: A Historical Perspective 

Session Begins:  1:00PM (EDT) / 12:00pm (CDT)

The jewelry industry and gem markets have seen great change and development in recent years. Markets have experienced both growth and fluctuation on a massive scale. New world records are set and then broken, and sales results are constantly discussed, but often without a larger context. Much of our price and value knowledge comes from modern, living memory, but what do we know about gem pricing in the recent and even distant past? How have we got to where we are today, compared with a hundred, or more, years ago, and how has our concept of prices and value changed? And furthermore, can this help indicate where we are going? Helen will address the importance of history, historical examples and models, and investigate shifts in the gem market from the perspective of the bigger picture.


Helen has a broad commercial, international and academic background in the gem and jewelry industry. For nearly 25 years she has worked with the trade, gemological laboratories, museums, and auction houses across Europe and Asia. She spent ten years as a jewelry specialist for Sotheby’s and Christie’s in London, where she handled and ran sales of global importance including the private jewelry collection of HRH The Princess Margaret in 2006. She has since held roles as Professeur d’Histoire du Bijoux at the Geneva University of Art and Design, Managing Director at the house of Gübelin, and is now Head of Jewelry at the Victoria and Albert Museum in London.  

Helen has a degree in Classics from Christ Church, Oxford, is a Fellow of the Gemmological Association of Great Britain, a Fellow of the Society of Antiquaries in London, and has published and lectured widely on gems and jewelry. Her forthcoming book Precious, a personal insight into the history of gemstones, will be published with Penguin in Spring 2024.
