The American Museum of Natural History is a New York institution, dating back to 1869. Since the 1970s, one of the museum’s permanent exhibitions has been an impressive showcase of gems and minerals. As a part of the museum’s 150th birthday celebration, this exhibition was overhauled, receiving a complete redesign, including a new floor plan, new specimens, and way more information. The new Allison and Roberto Mignone Halls of Gems and Minerals reopened this summer, after being closed for several years. It was well worth the wait, as the new gallery is stunning and full of fascinating educational resources describing “how the vast diversity of mineral species arose on our planet, how scientists classify and study them, and how we use them for personal adornment, tools, and technology.” The new exhibition features everything from huge glittering geodes to multicolored crystal formations and cut precious gemstones. There are specimens from 98 countries around the world, and many from right here in New York. Educational and beautiful, the new exhibition is a must-see part of one of our favorite museums in New York City.
