The Smithsonian gem and mineral collection contains an amazing array of Gold, Silver, and rare metal compounds. Many of the Gold and Silver specimens are among the finest for their localities, and there are also many examples from unusual localities. While not all the minerals show here are composed of precious metals, they are still rare and unusual examples of metallic compounds, especially sulfosalts.
