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.
Structure
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. We have sold the Disc form called Pyrite Sun, Spheres formed of hundreds of squares, Cubes of near square, Octahedral crystal form and crystal cluster forms.

PYRITE SUN
A stunning Pyrite Sun. This is a natural formation of Pyrite and something quite different to the usual more cubic looking varieties. Striations radiate out from the centre. Our Suns are hand selected at the source for their excellent quality. We are well known for our metals range and have pyrite specimens showing cubic, orbicular and octahedral crystals, as well as these suns. Pyrite (“fools gold”) is popular with all age groups. A great piece for the collector of unusual pieces. This Pyrite Sun comes with a perspex stand for display and looks even better in person.

SPARKLING PYRITE CRYSTALS
Beautifully simple Sparkling Pyrite Crystals with very reflective faces. Great addition for mineral, metals or pyrite collections. The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide which has the chemical formula FeS2. This mineral’s metallic luster and brass yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool’s gold. Interestingly Pyrite does not attract a magnet. This specimen comes from a premier location and sports a mini cave cavity right through.
