In early December, the Smithsonian Institution's National Museum of Natural History in Washington, DC, announced that the world's largest cut aquamarine would go on permanent display. The obelisk-shaped Dom Pedro Aquamarine, mined in Brazil in the 1980s, stands 14 inches tall, measures 4 inches across the base and weighs 10,363 carats or 4.6 pounds. It will join many other significant gems and minerals, including the famous Hope Diamond, at the NMNH's Janet Annenberg Hooker Hall of Geology, Gems and Minerals.
