Name a famous rock on exhibit at the Smithsonian Institute in Washington DC?

Answer 1

There are a number of famous "rocks" on display at the various Smithsonian museums.

The Air and Space museum has actual rock samples from the moon.
The Natural History museum has the Hope Diamond, and lots of other gemstones
Lots of meteorite samples are on display at the Natural History museum.


Here is what the Smithsonian has to say about its mineral sciences collections:

The U.S. National Meteorite Collection is one the largest and among the best museum-based collections of meteorites in the world, particularly strong in iron meteorites.

The National Gem and Mineral Collection is one of the greatest collections of its kind in the world with highly prized objects in the National Gem Collection as well as comprehensive mineralogical reference material. There are over 375,000 individual specimens in the collection including such famous pieces as the Hope Diamond and the Star of Asia Sapphire.

There are 14 discrete collections within the National Rock and Ore Collection. These collections together number about 265,000 catalogued and computer inventoried specimens with an additional 50,000 specimens awaiting curation. Large and very well documented collections of mantle xenoliths, ocean basin lavas, ores and edifice and eruption keyed volcanic rocks have worldwide coverage.

The Ore Collection (19,221 specimens) is a systematic collection of metallic ores and mineral commodities. The collection includes metal-bearing minerals and massive ore-bearing material (primarily from major U.S. mines opened prior to 1930).

Bottom line, if its rocks your interested in, the Smithsonian is the place to visit!
