Pyrite Chunks

Pyrite, otherwise known as fool’s gold,is an iron sulfide and one of the most common sulfide minerals.  These crystals usually form in cuboid crystals and sometimes can form in framboids due to the close association.  Also, in the right circumstances, pyrite can form amazing anastomosing filaments, or T-shaped crystals. Some can form to almost perfect dodecahedral shapes which is a polyhedron with 12 flat faces.  Pyrite has a metallic luster and pale brass-yellow hue which is why is has such a resemblance to actual gold, and hence the nicknamefool’s gold.  Even though pyrite looks as if it’s real gold, it is very distinguishable from actual gold due to its hardness, brittleness, striations, and the way the crystals form.
