Aquamarine Self Portrait

This is an accidental self-portrait (selfie) standing in front of the Dom Pedro aquamarine in the
Smithsonian Institution National Museum of Natural History NMNH. Here is a Wikipedia description of the aquamarine.
The Dom Pedro aquamarine is the world's largest cut aquamarine gem. It was cut from a crystal originally weighing approximately 100 pounds (45 kg) and measuring more than 3 feet (0.91 m) in length. The stone was mined in Pedra Azul, in the state of Minas Gerais in Brazil around 1980, and named after the Brazilian emperors Pedro I and Pedro II. The blue-green gemstone was cut by Bernd Munsteiner into an obelisk form weighing 10,363 carats. The finished dimensions measure 14 inches (36 cm) tall by 4 inches (10 cm) wide. The jewel was donated to the Smithsonian Institution by Jane Mitchell and Jeffery Bland. It is housed in the National Museum of Natural History's Janet Annenberg Hooker Hall of Geology.
