5.4" Pyritohedral Pyrite Cluster - Peru
This is a large cluster of well defined pyrite crystals from Peru. It's 5.5" wide and weighs just under 3 lbs. Large specimens, with great luster and large crystals like this one are getting hard to find, as the mines in Peru have shut down the collection of pyrite by miners in recent years. An excellent display piece.
Pyrite or iron pyrite is commonly referred to as Fool's Gold because it's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, Pyrite was sometimes mistaken for Gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits. Smaller (druzy) crystal aggregates may give off beautiful glistening effects, and larger crystals may be perfectly formed, including fascinating cubes, penetration twins, and other interesting crystal forms.
