| 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. Common Shapes of Pyrite |
| This is a pyrite sun on a shale matrix; it formed about 310-350 million years ago in the Mississippian formation in a small area known as Randolph County, Illinois. Pyrite suns form between tightly spaced layers of shale, in coal mines. The pyrite was forced to grow in a laterally compressed, radiating manner, instead of a more normal cube or Pyritohedral shape that pyrite is more commonly known for. This unique pyrite specimen has been cleaned on both sides and the shale slate matrix has been stabilized. This specimen can be displayed with the Pyrite in place on the matrix or next to it. This total specimen (pyrite sun on matrix) measures approximately; 7 5" wide and 5.75” high and 1” thick and weighs 1.55 lbs (702g) The pyrite sun measures approximately; 3.4 x 3.1 x .3 inches (87 x 77 x 7mm) and weighs 4.5oz (128g) |

| 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. |
