Striated Pyritohedral Pyrite specimen from Peru
I suppose it's true that you just can't keep every excellent specimen you find...This one is from
our private collection...an amazing 2.98 pound plate of beautifully formed striated pyrite
crystals on a plate of pyrite. The front of this specimen is covered with formations of
pyritohedral and striated crystals. The base is fine granular pyrite with the back showing many
vugs filled with smaller pyrite crystals.
This one weighs 2.98 lb (1352g) and measures @ 6 x 4.6 x 2.5 inches (15.2 x 11.7 x 6.5cm).   
Pyritohedral Pyrite with Drusy Quartz with Pyrite inclusions  from Brazil
Very nice specimen of Pyritohedral pyrite covered partially with a drusy quartz layer that has
fine pyrite inclusions giving a "pyrite sprinkled" look to the quartz.  
This piece weighs 0.28 lb (128g) and measures 2.4 x 1.4 x 1.1 inches (61 x 36 x 29mm).

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.

Octahedral Pyrite specimen from Peru
This is a bright octahedral pyrite cluster specimen of beautifully formed pyrite crystals on a base of pyrite. There are
twinned and inter grown octahedral crystals. Check out the growth patterns on the faces of the Pyrites. This piece is
from the famous Huallanca District, Dos de Mayo Province, Huanuco Department, Peru a locality known for
producing exceptional Pyrite specimens. We procured this exceptional piece from the Smithsonian Mineral Museum
on our June 2013 trip.

This piece weighs 5.1 oz or 0.32 lb (146g) and measures 2.2 x 2 x 1.2 inches (5.7 x 5.3 x 3.1cm).  
Unusual Crystal Habits!
Pyrite
29.7 oz or 1.86 lb (843g) 3.4 x 3.1 x 2.8 inches
(8.7 x 7.9 x 7.2cm)

This amazing and rare specimen comes from the
Txi Industries Quarry in Midlothian, Ellis County,
Texas. This is an Old Stock specimen that was
originally procured by IKON Mining & Exploration
based in Fallbrook, California. (That ID card
included)
We found this specimen in an old rock shop in
Utah. It has been in our personal collection for a
few years now but we are now offering this rare
combination of dull pyrite with a cap of brighter
pyrite. These specimens are few and far
between and are a real desirable piece for any
Pyrite collection.

We have never seen crystal formations
like this in Pyrite! It is like layers of
leaf-like plates and triangles ...a really
different piece for the Pyrite Collector!
Texas Pyrite is normally a dull brass
color finish, not the bright gold shine.
This striking specimen of Pyrite Cubes on Matrix comes from Navajun, Logrono, La Rioja, Spain. The all natural pyrite cubes have
brilliant mirror-like lustrous crystal surfaces. The near-perfect cubic crystals are in the Marl matrix they were formed in. (In Spain the
matrix may also be called either Mergel or Seekreide).   The color is a brassy gold. The cubes on this specimen are nearly perfect
natural cubes - formed by Mother Nature and came out of the ground just like that. These near-perfect cubes on matrix from Logrono
Spain are highly prized specimens. We procured this exceptional piece from the Smithsonian Mineral Museum on our June 2013 trip.

This piece weighs 7.14 oz or 0.44 lb (202g) and measures 2.5 x 2 x 1.8 inches (6.4 x 5.1 x 4.6cm).
It has two cubes, one up to 0.71” (18mm) and another up to 0.5” (14mm)

Radial Pyrite Sphere
Here we have something truly Unique. It's a large ball of radial Pyrite from the Coal Mines of
Morocco! These pyrite balls are from a 2009 find in Morocco, and were all the rage at the
East Coast Gem and Mineral Show, and the Big Denver show. At each of those shows, only a
few dozen were available, and every single one sold in the first several minutes of Opening
Day! They were also in short supply at the Tucson Show in Arizona, where they sold out for
Very High Prices! These pyrite balls show a unique aesthetic, reminiscent of a starburst
pattern. They consist of radiating lineation’s of pyrite around a center of organic carbon.

These balls are found in coal seams within an obscure Moroccan Coal Mine, and form when
decayed organic plant matter begins to emit hydrogen sulfide gas. Because the organic
matter is also rich in iron, the hydrogen sulfide gas combines with the free iron and nucleates
around compact regions of reduced organic carbon to produce the iron sulfide commonly
known as pyrite. The Result is these wonderfully interesting spheres! Each striation in the
pyrite ball represents a single crystal of iron pyrite that demonstrates gross elongation about
its c-axis. This occurs in a process known as 'oscillatory growth'. If you look at the exterior of
the ball, you can see that each striated crystals terminates in a wonderful crystal shape. Very
Neat Stuff!
This is one whole Ball that has been intentionally split into two sections. These sections are a
perfectly matched pair that represents an entire ball. I've been holding this one back for a
while, and it is the LAST Matched-Pair that I have, so be sure to grab it while you can!! These
pyrite balls are so interesting; no collection would be complete without one!
This Particular specimen measures 2.78" (7cm) in diameter, and weighs a whopping 33.8 oz
or 2.1 lbs (958g) for both halves of the matched-pair.

Intergrown Pyrite cubes on Magnesite XLs from Hunting Hill Quarry, Rockville, MD
Very rare specimen of crystalized Magnesite especially with the intergrown Pyrite. An
excellent speciman from this locale

This specimen weighs 11.4 oz or 0.71 lb (325g) and measures
3
.2 x 2.5 x 1.3 inches (8.2 x 6.5 x 3.4 cm)
These are completely natural formations; they are not cut to shape. These cubes of pyrite from La Rioja, in northern Spain, are very
popular due to their natural, near perfect shapes. It is commonly agreed that the finest cubic pyrite crystals in the world come from
either Navajun (population 21), or Logrono (population 147,000), in the autonomous community La Rioja, Spain. These locations are in
sub-region “Rioja Alto”, which means the high country, or mountains. Exquisitely sharp, lustrous, near-perfect cubic crystals from this
locality are available as single cubes, clusters of penetrating twins, and cubes embedded in a light tan Marl matrix they were formed in.
(In Spain the matrix may also be called either Mergel or Seekreide). This specimen has 3 raised cubes that measure 0.77 and 0.59 and
0.49” (19.7 and 15 and 12.5mm) on the front side and 2 smaller partially raised cubes that measure 0.34 and 0.19” (8.8 and 5mm) on
the back.
It is possible in the matrix specimens that some of the cubes may become dislodged from their location during shipping. It has become
an acceptable repair to glue the cubes back into their original position in the host rock in the position it naturally occurred.  While
repaired mineral specimens do detract from the value in most cases, this is one of the few specimen type exceptions that repairs are
acceptable to mount the cubes back in its original position.


This piece weighs 12.3 oz or 0.78 lb (351g) and measures 3.8 x 2.4 x 2.2 inches (9.7 x 6.2 x 5.7cm).
