Prim, who will explore forgotten gemstone designs observed through antique jewelry and art; and Jolyon Ralph, founder of Gemdat.org and Mindat.org, who will lead an interactive session on the use of online resources for gemological data and education.
A sixth session also has been added featuring Fatima Almahmood, a research scientist at The Bahrain Institute for Pearls & Gemstones (DANAT), who will talk about the natural pearl beds of Bahrain.
