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.
A continental collision about 1 billion years ago buried, heated and folded the layers of mineral-rich ore and marble, Verbeek said. Later exposed by glaciation and discovered by North Jersey early iron miners, the area’s iron-, zinc- and manganese-laced ore was commercially extracted until 1986.
The slab set for display was cut in late 2017 using a $6,000 diamond-studded cable laced through guide holes and powered by a generator. Initially due for presentation in 2019 as part of the $30 million renovation, the slab will sit in the 11,000-square-foot Allison and Roberto Mignone Halls of Gems and Minerals near other exhibits including:
The 632-carat Patricia Emerald
