Pyrite Mineral Unpolished

Pyrite is a fascinating mineral that crystallises in many different shapes. 

Also known as iron pyrite and fools gold, this naturally occurring material occurs worldwide in small quantities within sedimentary, igneous and metamorphic rocks.

The Rio Tinto mines of Spain produce vast quantities.  Bolivia, Brazil, Peru, Japan, Canada, Italy, Norway, Portugal, Greece and Slovakia have also been known to produce fine specimens.

Although relatively hard pyrite is brittle so will chip or shatter if knocked or dropped.  It does not react well to moisture so should not be allowed to get wet.

The flat crystal face of this pyrite mineral is highly reflective. 

This piece would have been cleaned up after being excavated but is otherwise untouched.
