Experiments and the high density of diamonds tell us that they crystallize at very high pressures.

No matter where you find mineral salt—on your table or at the beach—you'll see its unique cube-shaped crystals. Take a sweet look at the crystal patterns and compositions of minerals.
Jade has been used by people around the world for thousands of years—first to make tools, later to create precious works of art. Take a peek into mineralogist George Harlow's scrapbook to see why he thinks this rock is so special.
Whether 4.5 billion or 900 years old, every rock has a story to tell, giving us clues about the history of the Earth. Explore these stories by looking at igneous, sedimentary, and metamorphic rocks.
Zircons are tiny crystals with a big story to tell. Some of these minerals are the oldest Earth materials ever discovered, and therefore yield clues about what the planet was like after it formed 4.5 billion years ago. In this new Science Bulletins video, travel to a remote island off Greenland's coast and a zircon-making lab in New York State to learn how geologists are using these time capsules to build new hypotheses about the early Earth.
Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Each Bulletin is produced by AMNHs curatorial and scientific staff and a team of video producers, designers, writers, and educators using state-of-the-art technologies such as high-definition video, data visualization, and 3-D computer graphics to present the latest research.
