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.

Information about crystals/mineral specimens from this location
Here's 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.
Facts about gems, rocks and minerals
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.
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's 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.
Although 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.
Information about crystal, gem and mineral metaphysics and healing
People 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.
