Title | Native silver from Lowell, Arizona |
Description | Native silver is rare. Today most silver is produced from silver-bearing minerals such as prousite, pyrargyrite, and galena. Specimens of native silver usually consist of intertwined wires. Silver tarnishes when exposed to air, and so is typically gray or black and rarely has a bright silvery metallic luster. This sample is 5 cm across. |
