Most silver is extracted from silver ore s, but considerable amounts are mined from Native Silver. Silver can be found pure, but is usually mixed with small amounts of gold, arsenic, and antimony. A natural alloy of gold and silver is known as Electrum, and is usually classified as a variety of Gold. Silver is a very resistant mineral.

The discrepancy between gold content of electrum from modern Western Anatolia (70–90%) and ancient Lydian coinage (45–55%) suggests that the Lydians had already solved the refining technology for silver and were adding refined silver to the local native electrum some decades before introducing the pure silver coins cited below.

Almost all silver deposits found do not produce a lot of native silver specimens. The exceptions are places like Kongsberg, Norway, some of the old German silver mines, as well as the Michigan copper/silver mines. Native silver is rarely discovered, even today. A replica underground exhibit gives visitors an idea of silver mining in Kongsberg.

Most widespread minerals containing Silver; This list of minerals containing Silver is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Silver mineral species.

The Native Silver covers the surface of a granular, somewhat etched matrix of tan-cream Calcite. The Acanthite forms equant crystals of up to 3 mm diameter in clustered stacks, on and adjacent to contorted, arborescent branches of Acanthite-coated Native Silver.

Native silver is sometimes found in the oxidized zones above the ores of other metals. It persists there because silver does not readily react with oxygen or water. It does react with hydrogen sulfide to produce a tarnished surface that is composed of the silver sulfide mineral known as acanthite.

Native Silver is rare and much silver is produced from silver-bearing minerals such as prousite, pyrargyrite, galena, etc. Specimens of Native Silver usually consist of wires that are curved and intertwined together, making an inspiring mineralogical curiosity. In
