Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. 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.

Pyrite is the rarest and most valuable ore in Cataclysm. It sells from 5 gold to 10 gold depending on what realm you're on and often sells best in stacks of 1. It's currently used by Jewelcrafters to prospect rare and uncommon gems and is expected to become the source of epic gems later in Cataclysm (this is highly controversial).
