Minerals, Earth and Space

Earth is a dynamic, ever-changing planet.

Earth formed as part of our solar system more than 4.5 billion years ago. It has been shaped by powerful geologic forces over its entire history and will continue to change for billions of years to come. Societies depend on Earth’s vast mineral and energy resources and on a climate that allows life to flourish.

In the Mineral Galleries at the Peabody, you can learn more about the Solar System, how minerals are formed, gems and jewelry, and the history of mineralogy at Yale. David Friend Hall, the largest gallery, features artistic presentations of remarkable minerals from around the world.
