Silver, a soft, white and lustrous metal, is usually found in native form as an alloy with other metals and in minerals, such as argentite and chlorargyrite. Among all metals, its malleability and ductility offer high levels of optical reflectivity as well as excellent thermal and electrical conductivity.

Chlorargyrite, despite being an important ore of silver, is not well-represented in collections. This is because of its general lack of aesthetics, with the bulk of mined material being processed for the extraction of its silver content. Formerly called Cerargyrite, Chlorargyrite is the currently accepted name of this mineral today.

Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with these or alloyed with other metals ...
