The giant blue whale and equally massive dinos might get all the glory at the American Museum of Natural History, but a new acquisition is bringing another exhibit into the extra-large club. This morning, the institution unveiled a 12-foot-tall, 9,000+ pound amethyst geode from Uruguay (one of the largest in the world) that will anchor its all-new Halls of Gems and Minerals. Ralph Appelbaum Associates is handling the renovation of the 11,000-square-foot space, which is being designed in anticipation of AMNH’s upcoming $340 million expansion by starchitect Jeanne Gang. The Halls previously ended in a cul-de-sac but the new Halls will feature a “stunning Crystalline Pass."
