17th century traders who traveled the sea routes between India and Southeast Asia were interested in spices, but they were also interested in gemstones, objects of desire, commercial value, and increasingly, scientific fascination. Claire Conklin Sabel talks about the gem trade in South and Southeast Asia, and the way this trade was impacted by European traders in the 17th and 18th centuries. Sabel is a historian of early modern earth science and a post-doctoral researcher at the University of Vienna. She is working on her a book project, Rare Earth: Gemstones, Geohistory, and Commercial Geography c. 1600-1750.
