New York City is getting its sparkle back. The American Museum of Natural History will reopen its popular Allison and Roberto Mignone Halls of Gems and Minerals to the public this weekend following a $32 million redesign. The galleries feature more than 5,000 specimens sourced from 98 countries, including a 563-carat Star of India sapphire, a 12-sided 632-carat Patricia Emerald, and a 14,500-pound slab with huge garnet crystals found in upstate New York.
