can't help but be amazed by the near perfection of this large pyrite
cube. The crystal is as nearly perfect as a pyrite crystal of this size
can be. It is brilliant and lustrous, reflecting light off of each mirror
bright face. The edges of the crystal are razor sharp, and the cube
has all 90 degree corners. The color is a bright silvery/brassy gold.
There is only minor damage on 2 corners.

about crystals/mineral specimens from this location
a beautiful specimen of brassy golden PYRITE (also known as fool's
gold) that's a near-perfect cube. Its faces are shiny mirror-like and
smooth, with very faint growth lines to prove it wasn't polished. The
piece comes from the classic locality at Navajun, Logrono, Spain. This
is a natural cube - formed by Mother Nature so almost-perfectly that
it looks as if it were machined. The most common question people ask
about these is, "You mean they came out of the ground just like
that?" Yup! I found this fabulous specimen out in Tucson in the
room the man who operates the mine in Logrono, and brings the year's
best finds to the Tucson Gem Rock and Mineral Show to sell.
about gems, rocks and minerals
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.
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.
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.
structure is analogous to galena's structure with a formula of PbS.
Galena though has a higher symmetry. The difference between the two
structures is that the single sulfur of galena is replaced by a pair
of sulfurs in pyrite. The sulfur pair are covalently bonded together
in essentially an elemental bond. This pair disrupts the four fold symmetry
that a single atom of sulfur would have preserved and thus gives pyrite
a lower symmetry than galena.
pyrite is common and contains a high percentage of iron, it has never
been used as a significant source of iron. Iron oxides such as hematite
and magnetite, are the primary iron ores. Pyrite is not as ecomonical
as these ores possibly due to their tendency to form larger concentrations
of more easily mined material. Pyrite would be a potential source of
iron if these ores should become scarce.
has been mined for its sulfur content though. During WWII, sulfur was
in demand as a strategic chemical and North American native sulfur mines
were drying up. A sulfide deposit near Ducktown Tenn. was found to be
able to mine pyrite and other sulfides such as pyrrhotite and pentlandite
and produce the needed sulfur as well as iron and other metals. The
sulfur was used in the production of sulfuric acid, an important chemical
for industrial purposes. Now most sulfur production comes from H2S gas
recovered from natural gas wells.
about crystal, gem and mineral metaphysics and healing
interested in metaphysics and crystal healing tell us that pyrite is
one of the most protective stones in use today. It can shield one from
many types of negative energy. It is also an excellent healing stone,
and as a representative of the Sun's golden energy it can help one to
see through facades.
