AMNH. Mignone Halls

The American Museum of Natural History (AMNH) offers an extraordinary experience. Home to over 100,000 specimens, including around 5,000 gems and minerals from nearly 100 countries, many of which have never been displayed before, the collection is truly vast. Among its iconic treasures are two massive amethyst geodes from Uruguay, standing 9 and 12–13 feet tall—some of the largest publicly exhibited geodes worldwide. The Star of India, a remarkable 563-carat star sapphire, and the Patricia Emerald, a rare uncut 632-carat gem from Colombia, highlight the hall’s unique offerings. Other notable pieces include the Subway Garnet, a 9-pound almandine found beneath Manhattan, and the impressive 3-foot-tall elbaite tourmaline known as Tarugo.

Beyond these spectacular specimens, visitors can explore interactive displays that delve into mineral evolution, illustrating how over 5,500 mineral species have emerged throughout Earth’s history. Hands-on elements like the periodic table and the “Minerals of New York” segment make learning engaging, while immersive lighting and illuminated cases bring out the optical beauty and intricate structures of each specimen.
