There are about 114,000
specimens in the Museum's collection: 90,000 minerals, 20,000 rocks, and
4,000 gems. The Newmont Azurite, found in a Namibian mine in 1952; the Star
of India, world's largest blue star-sapphire; and the Patricia Emerald, an
exceedingly rare specimen found in the Colombian Andes in 1920, are among
visitors favorites.
