The E. Hadley Stuart, Jr. Hall of Gems and Minerals displays more than 2000 spectacular specimens within two large galleries that comprise what is considered to be one of the finest exhibits of gems and minerals in the world.
Overall, the exhibit features an incredible array of gems and minerals from all over the globe as well as an extensive collection of California specimens. The objects in the gallery are so beautiful, you can’t help but want to touch them. Luckily visitors are encouraged to interact with multiple “touch specimens” of gems, minerals and meteorites. A slab of gem-quality jadeite, weighing several hundred pounds, is one of the most valuable specimens in the entire exhibit and must be one of the most valuable mineral specimens available for public handling in the world.
The Hall of Gem and Minerals houses only a small fraction of the Museum’s extensive collection, which now includes more than 150,000 specimens.
(From the Benitoite Gem mine, San Benito County, California)
California's official state gemstone, benitoite occurs in gem quality at only one place in the world, a mine in the Diablo Range of San Benito County, California. This unique wreath-like intergrowth is one of the finest known specimens of the gem.

(From the Cruziero mine, Minas Gerais, Brazil)
The Cruzeiro mine has long been one of the world's largest producers of fine gem tourmaline. This specimen, found in 1972, is one of the most dramatically beautiful to come from the mine.

(From Kongsberg, Norway)
This natural silver "wire" came from the famous mines at Kongsberg, Norway. These mines operated continuously from 1623 until 1957, yielding some of the most beautiful specimens of silver known.
(From the Little Three mine, San Diego County, California)
The bright orange spessartine gemstones from the Hercules Dike at the Little Three mine are regarded as among the finest in the world. This specimen, found in 1987, is the finest known from the mine.

(From the Groundhog mine, Gilman, Colorado) Appearing much like a "ram’s-horn", this natural wire gold is one of the finest known. It was found around 1878 and is said to have once belonged to Dr. David H. Dougan, the first mayor of Leadville, Colorado.
