Allison and Roberto Mignone Halls of Gems and Minerals

A treasure returns to New York City.

Opening February 17, 2021, these reimagined halls will offer a brilliant showcase for one of the world’s most important collections of gems and minerals.

Remarkable new specimens and familiar treasures—including two amethyst geodes which, at 12 and 9 feet tall, are among the world’s largest on public display, a 3,000-pound block of iridescent green and blue labradorite, the legendary 563-carat Star of India sapphire, and the 632-carat Patricia Emerald—will reveal the extraordinary diversity and beauty of gems and minerals that are found on our dynamic planet.

Exhibits featuring about 5,000 specimens from 95 countries will tell the fascinating stories of how mineral diversity arose, the environments in which minerals form, how scientists classify them, and how humans have used them throughout history for personal adornment, tools, and technology.
