Acanthite

Acanthite could be the most important silver ore. Galena is a lead ore that often contains enough silver (usually about 1%) that when it is processed for its lead content the by-product silver supplies the majority of the world's needs. Most of all the silver in galena is thought to be microscopic inclusions of acanthite crystals.

Acanthite is the low-temperature modification of silver sulphide. All natural silver sulphide specimens at room temperature are Acanthite. The tarnish on Sterling is acanthite.

Acanthite is generally easily identified although it may appear like galena and other silver sulfide minerals. Acanthite is sectile which means that it can be cut into by a knife just like lead. Acanthite is generally a very valuable mineral specimen, due mostly to the high silver content and the rarity of good crystals.
