Pyrite: The mineral pyrite information and pictures
Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities. Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

Sometimes cruelly known as ‘fool’s gold,’ pyrite is actually much harder than gold and often has flat crystal faces that would not occur in real gold. Although no longer considered a valuable mineral in its own right, pyrite in a rock often signals the presence of other hydrothermal minerals and metal ores that do have significant value.
