What is Pyrite?

Pyrite crystals belong to the sulfide mineral family. They are commonly found in sedimentary rocks such as limestone, shale and sandstone. This crystal is well known for being rich in iron sulfide. The iron is provided as a result of older igneous rocks weathering. Another important component is the action of bacteria that reduce sulfide. In these circumstances where iron and sulfide are present Pyrite crystals begin to grow. 

Pyrite stone ranges from 6 to 6.5 on the Mohs scale which makes it a hard crystal, but not as hard as Quartz members. There is an uneven and sometimes conchoidal fractures when the mineral is exposed to breakage. It can grow in a wide variety of formations such as cubic structures, dodecahedrons, chunky clusters, tiny druzy and so much more.

Pyrite’s name is derived from the Greek word “pyr” which means fire. This association with fire is significant because the crystal can emit sparks when it’s struck by metal.

 

The Geological Formation of Pyrite: How Does It Form?

Pyrite, an abundant sulfide mineral, forms in a variety of geological environments and is commonly found in sedimentary, igneous, and metamorphic rock types. This metallic mineral, composed of iron disulfide (FeS₂), crystallizes under conditions where both iron and sulfur are present in sufficient quantities.

Pyrite often occurs as a secondary mineral, meaning it forms as a result of chemical reactions rather than being directly deposited from a molten or primary state. It is frequently found in hydrothermal veins, where hot, mineral-rich fluids interact with existing rocks, depositing pyrite alongside calcite crystals, quartz, and other metallic minerals. Pyrite can also form in marine sedimentary environments, particularly in brown coal and shale formations, where it develops through the bacterial reduction of sulfate in organic matter.

Another fascinating form is auriferous pyrite, which contains trace amounts of gold within its structure. These gold-rich pyrites are a significant source of iron and precious metals in mining operations. Some types of pyrite contain arsenic in pyrite, making them valuable for scientific study and mineral extraction.

Pyrite can also be found in fossilized organic matter, replacing biological material over millions of years in a process known as pyritization. This results in beautifully preserved fossils with a metallic iron sheen, often found in black shales and coal seams.

 

Fool's Gold

Pyrite’s shiny yellow appearance may make someone unfamiliar with the stone think that they have struck gold. Because this is so common, Pyrite has been given the nickname “fools gold.”   The term "Fool's Gold" has been used for centuries to describe Pyrite. Its use dates back to ancient civilizations, and it's not attributed to a specific individual or a precise moment in history. The name “Pyrite” is Greek for “stone or mineral which strikes fire.” In the 16th and 17th centuries, Pyrite was used as a source of ignition in firearms.  People can often also call it Iron Pyrite.

Iron Pyrite

The nickname "Iron Pyrite" is also bestowed upon this remarkable crystal is a direct nod to its elemental composition. Pyrite stone is primarily composed of iron (Fe) and sulfur (S), with the iron content being a significant component of its molecular structure. This chemical makeup is often referred to as iron sulfide, which accurately describes Pyrite's mineral composition. This nickname, Iron Pyrite, while scientifically accurate, also adds to the crystal's mystique and allure, highlighting its unique combination of elements that gives rise to its radiant appearance and intriguing properties.

 

Other Common Types of Pyrite

1. Cubic Pyrite – The most recognizable form, featuring well-defined cube-shaped crystals. Often found in sedimentary deposits, particularly in Navajún, Spain, where near-perfect cubes form naturally.

2. Pyritohedral Pyrite – Displays a dodecahedral crystal habit with pentagonal faces, giving it a unique, slightly rounded appearance. Found in hydrothermal veins and sedimentary rock types.

3. Octahedral Pyrite – Characterized by its eight-faced octahedral crystals, which are rarer than cubic formations. This variety is commonly associated with calcite crystals and quartz.

4. Framboidal Pyrite – Consists of microscopic, spherical clusters that resemble raspberries. Frequently found in brown coal deposits and organic matter, particularly in marine sedimentary environments.

5. Marcasite on Pyrite – A mixture of marcasite and pyrite, with marcasite forming a silvery coating or intergrown structures on the pyrite surface. Often found in fossilized shells and pyrite fracture-surfaces.

6. Pyrite Suns (Pyrite Dollars) – Disk-shaped formations that develop in shale layers under high pressure. Most famously found in Illinois coal mines, these specimens have radiating crystal patterns resembling the sun.

7. Auriferous Pyrite – A gold-bearing pyrite, containing microscopic inclusions of gold within its structure. This variety is a significant source of gold extraction in mining.

8. Botryoidal Pyrite – Forms in rounded, grape-like clusters rather than distinct crystal shapes. This variety often occurs in hydrothermal deposits and volcanic rock types.

9. Massive Pyrite – Lacks distinct crystal faces and appears in large, granular masses. Commonly found in sedimentary and metamorphic rocks, particularly in coal seams.

10. Pyritized Fossils – Occurs when organic matter, such as shells or wood, is replaced by pyrite over time. This preservation process, known as pyritization, creates highly detailed, metallic-looking fossils.

 

What does Pyrite look like?

Pyrite is an opaque iron sulfate mineral that is easily identifiable because of its metallic, brassy-yellow coloration and cubic structure. Pyrite forms in cubes among other formations, and can range from being one large cube to hundreds of small crystals in one stone. Pyrite is typically sold in its raw form, which may look dull and tarnished until polished.  But it is also popular as a raw crystal formation due to the sparkles.  Even when the stone is tumbled, it will have many holes or divots in it. Because of pyrite’s grown patterns it is often a very sparkly crystal even in its more chunky formation.

 

You can also identify Pyrite by the greenish-black streaks it leaves behind when scraping an object harder than it.

Pyrite is also often a stone that is mixed in with many other stones such as Serpentine stone, Rhodonite, Bloodstone, Lapis and many more.  You can sometimes see full cubes in the formation and sometimes it is just small flecks.

 

Where is Pyrite found?

Pyrite is the most abundant sulfide that can be found in tons of localities. Some noteworthy mines are in Italy, Peru, Spain and multiple states in the US like Montana, Washington, Missouri, Colorado, Arizona and others. 

Pyrite is a common mineral that can be found in a variety of geological settings. It can be formed in sedimentary, igneous and metamorphic rocks, and is often associated with gold deposits. The largest deposits of pyrite are found in sedimentary rocks, where it forms as nodules, concretions, and layered deposits. Pyrite is also commonly found in hydrothermal veins, which are formed when hot fluids from magma or heated groundwater move through fractures in the earth's crust. In these settings, pyrite is often associated with other sulfide minerals like chalcopyrite crystal, sphalerite, and galena.

Another interesting fact about pyrite is that it can be found in the fossilized remains of ancient organisms like ammonite fossils, where it has replaced organic materials like shells and bones. This is known as pyritization and is a common occurrence in marine sediments. Overall, pyrite can be found in a wide variety of geological settings all around the world, and is a fascinating mineral to study for its unique properties and formations.

How to Identify Genuine Pyrite vs. Fake Pyrite

Pyrite is often mistaken for gold, but several tests can help differentiate between the two:

1. Hardness Test

Gold is soft and can be scratched with a fingernail, while pyrite is harder (6-6.5 on Mohs scale) and resists scratching from common objects.

2. Streak Test

Rub the mineral on an unglazed ceramic plate. Pyrite leaves a greenish-black streak, while gold produces a yellow streak.

3. Pyrite Fracture-Surfaces

Pyrite has a brittle fracture with conchoidal (curved) surfaces, whereas gold bends and does not break easily.

4. Specific Gravity

Gold is much heavier than pyrite. If you compare two similar-sized pieces, the gold specimen will feel significantly denser.

Industrial and Commercial Uses of Pyrite

Despite being known as fool’s gold, pyrite has played a significant role in human industry. Historically, it was a source of iron for early civilizations, and today it remains a key material in several industrial applications.

1. Sulfuric Acid Production

One of the primary uses of pyrite is in sulfuric acid manufacturing. When heated, compounds of iron and sulfur in pyrite release sulfur dioxide, which is then converted into sulfuric acid. This acid is essential in numerous industries, from fertilizer production to petroleum refining.

2. Use in Energy and Batteries

Recent research has explored the potential of anisotropic pyrite in solar cells and lithium-ion batteries. Scientists at American Mineralogist have found that metallic iron sulfides like pyrite may serve as sustainable energy materials due to their semiconductor properties.

3. Fire Starters and Historical Uses

The Greek name for pyrite, meaning "fire stone," originates from its ability to create sparks when struck against metal. This property made pyrite an essential material in early firearms, particularly wheellock guns.

4. Decorative and Jewelry Uses

Although pyrite is too brittle for widespread use in jewelry, pyrite jewelry pieces, particularly in marcasite jewelry, became popular in the Victorian era. Today, marcasite on pyrite settings are still used in silver jewelry for a vintage aesthetic.

 

Crystals that look like pyrite

There are two very similar looking crystals that are often mistaken with Pyrite.  Chalcopyrite is also an iron sulfate, but their chemical composition is different.  Chalcopyrite will typically have a natural iridescent (or mix of colors) appearance. It can vary from a subtle coloring to a very vibrant color as is the case with Reynold's chalcopyrite and the ones from Mexico that often take on the name 'peacock ore' due to their coloring. BUT, it can be just a gold coloring, but typically more of a yellow gold than pyrite.

Marcasite is also very similar, but has a different internal crystalline structure to it. It also tends to form differently in visual appearance. You may remember marcasite from vintage jewelry like lockets that appeared to be a brassy color.
