Pyrite
Pyrite is the classic "Fool's Gold". There are other shiny brassy yellow minerals, but pyrite is by far the
most common and the most often mistaken for gold. Whether it is the golden look or something else,
pyrite is a favorite among rock collectors. It can have a beautiful luster and interesting crystals. It is so
common in the earth's crust that it is found in almost every possible environment, hence it has a vast
number of forms and varieties.
Unlike gold, which is prized because of its color, brightness, workability, and rareness, Pyrite is not a
metal, but rather, a sulfide made up of iron and sulfur. Pyrite is much harder and more brittle, and it
tarnishes to a dark brown. Fool's Gold is very common, and this has led to many people thinking they
had discovered real gold over the years. Pyrite forms when hydrogen sulfide combines with iron. These
common elements often fuse and are carried by heated fluids to cracks in native rocks where pyrite is
deposited. It is attractive, and many museums keep specimens of Pyrite for display or educational
purposes.
Bravoite is the name given to a nickel-rich iron sulfide. It is closely related to pyrite but contains up to
20% nickel. Some mineral books treat it as a variety of pyrite. Pyrite is a polymorph of
Marcasite, which
means that it has the same chemistry, FeS2, as Marcasite; but a different structure and therefore
different symmetry and crystal shapes. Pyrite is difficult to distinguish from Marcasite when a lack of
clear indicators exists.

Pyrite Sun from Sparta, Illinois.  Pure Pyrite
crystallization with no matrix featuring radiating
golden crystals that sparkle in the light.  These are
also known as Pyrite Dollars and Sun Dollars.  
Collected in a coal mine hundreds of feet below
the earth's surface, this sun formed over 300
million years ago!  Fanned crystal structure is due
to compressed growth between sheets of slate.

Globular Pyrite on Barite
We found this pyrite at an estate sale in South Carolina in a box marked "Pyrite in
Baryte, Germany" We purchased this piece because we believe it came from the
Christiane Mine in Adorf, Diemelsee, Hesse/Hessen  Germany  which was a former iron
mine that was abandoned in 1963. We had a very similar piece from that locale several
years ago. That however, is just our opinion...we only know for sure that it came from
Germany, it is old stock and has the number 129 on the bottom.  
This weighs 1.24 oz (36g)
and measures 1.7 x 1.3 x 0.8 inches (45 x 33 x 20mm).

Pyrite Plate from the Racracancha Mine, Tinyahuarco District, Cerro de
Pasco Province, Pasco Department, Peru.

Racracancha is an abandoned mine that was reactivated by local mineral miners in
2007. Current operations are limited to hand collecting mineral specimens of flashy
striated pyrites the mine is known for. Peruvian specimen mines rarely have any heavy
machinery which means that miners are limited to working old digs. Precious little high
quality material has been found over the past few years. This specimen is an excellent
example of quality crystal plate from this classic locale. This has been in our personal
collection since 2008.
This weighs 12.9 oz or 0.8 lb (366g)
and measures 3.5 x 2.7 x 0.44 to 1.2 inches (89 x 68 x 11.4 to 31.5mm)
