PYRITE SUN SMALL
A stunning Pyrite Sun Small. 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. This size specimen is perfect for pendant jewellery making.

Pyrite, Iron Sulfide FeS2.
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.
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. 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.
