Seminar Lab Detail:
Summary: The Hope Diamond is one of the most famous gemstones in the world. It is familiar to most people because of its fascinating human history that includes kings and thieves and perhaps a curse or two, but it is also a rare blue diamond, the largest and finest of its kind known. Despite its long history in the public eye, the diamond still prompts many questions. The United States National Gem Collection at the Smithsonian Institution is also well-known for its many other world-class gems and jewelry pieces. Curator-emeritus, Jeffrey Post, will explore the science and lore behind some of the famous and lesser-known gems in the National Collection.
