Gems at The American Museum of Natural History

The Gems and Minerals exhibits at the American Museum of Natural History have come back home to New York City where visitors can marvel at samples of vibrant, colorful and otherwise interesting products of our planet's geological churnings. Dr. George Harlow, a geologist and curator of the Allison and Roberto Mignone Halls of Gems and Minerals, joins us to talk about the rocks and minerals on display, how nature made them, and how humanity has integrated these materials into its culture. Plus, we get a peek at the museum's other exhibitions, including their "Creatures of Light: Bioluminescent Animals Exhibition."
