Since joining GIA in 2015 at the Thailand laboratory, Wim has participated in GIA Field Expeditions on different continents focusing on ruby, sapphire and emerald mining areas. During these expeditions, samples are collected for GIA’s research and the local situation is documented. He has (co-)authored articles on new gemstone localities, updates on existing mining localities, in-depth gemological studies and treatment experiments. In his role as manager, Wim is overseeing the field gemology department and is in charge of GIA’s colored stone research collection in Bangkok.
Field gemology is more than just studying gems in the field. It is trying to better understand how gemstones impact everything surrounding them, whether that is the environment or the people working with them. It is only when we understand the full picture of the gem that we’ll start to appreciate the true value of these special items. It is critical for all of us to develop a holistic view of our gems, while also recognizing that could mean different things for every individual or organization. During this presentation, we’ll take a look at how gemstones, communities, mining and the source are all connected and how understanding these complexities can help us address challenges we face daily.
