The hall has been completely renovated to showcase "nature's art."

Four years ago, the Halls of Gems and Minerals at New York’s American Museum of Natural History closed for long-overdue renovations. The cavelike space, deliberately designed to evoke the feeling of the mines where many of the specimens on display had been excavated, had been essentially untouched since 1976.

This week, it reopens to the public and features some 5,500 objects, from polished diamonds to rough-hewn sandstone.

“I think it’s fair to say that no space, no gallery is quite as glittering as these new halls,” museum president Ellen Futter said at the press preview.

The 11,000-square-foot halls have traditionally been one of the museum’s most beloved attractions, and the museum is predicting that it will be a major draw for tourists returning to the city.

“There is something truly elemental and visceral about our connection to the minerals and materials of the earth on which we live,” Futter said. “Didn’t we all collect rocks as children?… And who among us doesn’t appreciate a spectacular gem?”

Remade by exhibition design firm Ralph Appelbaum Associates courtesy of benefactors and new namesakes Roberto and Allison Mignone, the hall is virtually unrecognizable from the dark gallery with carpeted ramps and floor-level display cases it used to be.

“I called [it] the jungle gym and the nanny-dom,” George Harlow, the museum’s curator of the department of earth and planetary sciences, said at the press preview.

The entrance to the new galleries features a pair of towering amethyst geodes that are among the world’s largest on display. • The amethyst geode pictured here stands 9 feet-tall, weighs around 12,000 pounds, or about as much as four black rhinos, and was collected from the Bolsa Mine in Uruguay.

New explanations about the evolution of minerals also reflect the latest scientific research.

Today, the most widely accepted theory is that most of the 5,500 known minerals evolved in tandem with life. (The Earth has 10 times more minerals than anywhere else in the Solar System.)

The hypotheses, introduced in 2008, holds that there was an explosion in mineral diversification during the Great Oxidation Event that began some 3 billion years ago, introducing oxygen into the atmosphere and leading to boldly colorful minerals.

“Without minerals, there really isn’t life,” Harlow said. “Getting people to understand that we have a relationship with minerals makes them more approachable beyond the fact that they can be gobsmackingly beautiful.”

All minerals are naturally occurring solids with crystalline structures and uniform chemical compositions, but they can form in different ways, leading to dramatically different appearances.

Amethyst, citrine, agate, and jasper are all varieties of quartz. Rocks can contain several different minerals. Granite, for instance, is typically a mix of quartz, feldspar, and mica. And then there are the gems—cut and polished minerals that are hard and durable enough to be worn as jewelry.

New additions to the collection include the diamond and platinum Organdie Necklace, worn by Rihanna on the cover of Essence and donated by the New York jewelry dealer Siegelson.

The cream of the crop is perhaps the 563-carat Star of India sapphire, the world’s largest-known gem-quality blue star sapphire. The most famous piece in the museum’s gem collection, it was stolen in a 1964 jewelry heist and later recovered in a Florida bus terminal locker.

Part of the fun of exploring the hall is discovering all the unfamiliar mineral names: Wulfenite, Almandine, Cubanite, Proustite, and Tantalite, to name just a few.

Then there are the showstoppers, like the Singing Stone, a massive block of bright blue azurite and green malachite from Arizona shown at 1893 World’s Columbian Exposition in Chicago. It emits a high-pitched sound when the humidity changes. (An effect sadly not in evidence in the climate-controlled museum.)

Other highlights include the cherry red Tarugo, an Elbaite Tourmaline that at three feet tall is one of the world’s largest intact mineral crystal clusters. And then there’s a 10-ton rock from New Jersey’s Sterling Mine, which fluoresces in red and green when seen under ultraviolet light in a dramatic display.

But perhaps the most memorable are the two monumental amethyst geodes in the “Crystal Garden” display that greet visitors at the hall’s entrance. Striking in their otherworldly beauty, they measure nine and 13 feet tall and weigh in at over 12,000 and 9,000 pounds, respectively.

The 135-million-year-old specimens are from the Bolsa Mine in Artigas, Uruguay, and were created when gas bubbles in magma-formed cavities. As groundwater flowed in, dissolved silica turned into quartz, creating the stunning purple crystals.

“This is a piece of art,” Futter said. “It’s nature’s sculpture.”

Almandine Subway Garnet. This incredible 10-pound almandine is known as the Subway Garnet. It was discovered in 1885 under 35th Street between 7th Avenue and Broadway, near Herald Square. The name is misleading because it was actually found during excavation for sewer pipes. Photo by D. Finnin, ©AMNH.

Known as the Singing Stone, this massive 4.5 ton block of vibrant blue azurite and green malachite from Arizona was first exhibited at the 1893 World’s Columbian Exposition in Chicago. After it was first displayed at the museum, this block was dubbed the Singing Stone because of the high-pitched sounds it made when the humidity changed with the weather and seasons. Now that it is exhibited in a controlled environment, it has stopped singing. Photo by D. Finnin, ©American Museum of Natural History.

In 1902, transparent lilac-pink crystals arrived at the Tiffany & Company office of George Kunz, who helped establish the gem and mineral collections at the Museum. The sender believed they were tourmaline. Kunz, however, identified the crystals as a new variety of spodumene—the first that wasn’t yellow or green—and it was named kunzite in his honor. Photo by D.

Birthstones are associated with the 12 months of the year and the 12 symbols of the Zodiac, but the specific gems for each month or sign have varied over the centuries and across cultures. The list of birthstones common in the U.S. today dates back to the 1900s, when gemological organizations in the United States and Europe arrived at several standardized lists. The gems in the case represent four different cultural traditions. Photo by D. Finnin, ©American Museum of Natural History.

This case in the Gem Hall features organic gems—those originally produced by living organisms, like jet (formed from wood), coral (formed from exoskeletons), pearl (formed by mollusks) and amber (formed from tree sap)—and opals, which are brittle and often difficult to set as jewelry.
