It is the largest and most famous gem and mineral show on Earth, and one where the finest mineral specimens are displayed. There is no single location for display of minerals, but dozens: big hotels and most motels are occupied for that occasion, professionals even displaying their specimens in hotel bedrooms, lobbies, under tents, and on lawns all over town. It is estimated more than 35,000 people, from more than 20 countries attend the show, as expert or beginners collectors, museum employees, dealers, retailers, and researchers. Many museums and universities, such as the Smithsonian Institute and the Sorbonne, bring materials to display at the show.
