The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.
Pyrite deposits in many different forms. Most commonly occurring in a cube shape, it can also form in association with other minerals (quartz, inclusions in lapis lazuli, etc...). Pyrite can also be the mineral replacement in fossilization.
There are many excellent examples of pyrite at the show this week, from beautiful clusters of cubes, to pyritized (fossilized with pyrite) ammonites, and sand dollars.
