These totally natural Pyrite polymorph after Marcasite spherical nodules are from Java, Indonesia. Not only are they almost perfectly spherical they also display the clear Pyrite cubic formation on the outside.

This piece weighs 24g and has a diameter of approximately 2cm.

Despite the natural abundance of pyrite and marcasite and their intergrowth, the phase transformation from the thermodynamically metastable polymorph Marcasite to the stable polymorph Pyrite is yet to be fully understood.

A mineral is defined both by its chemical composition and its crystal structure. In some cases two different minerals have the same chemical composition, but different crystal structures. Known as polymorphs, these intriguing cases illustrate how the different crystal structures can result in quite different physical properties.

Pyrite has a cubic structure, metallic lustre and a yellow-gold colour that has earned it the nickname "fool's gold". With a hardness of 6 to 6.5 on the Mohs scale, Pyrite is hard enough to be used in jewelry. Pyrite is also exceptionally dense, with a specific gravity of 5.0 to 5.2, second only to Hematite.

Marcasite tends to be lighter in colour, and is sometimes referred to as White Iron Pyrite. Sometimes Marcasite has a greenish tint, or a multi-colored tarnish that is the result of oxidation. But Marcasite has an unstable orthorhombic crystal structure and is liable to crumble and break apart.


Marcasite has energies nearly identical to Pyrite, both offering up vibrations of magnitude and endurance while aligning one’s lower chakra system. For these particular pieces I am leaning toward Pyrite rather than Marcasite when it comes to their properties.

Pyrite is an enhancer crystal which means it helps enhance our focus in all aspects of life. Pyrite is also a mirror crystal. It reflects truth and reality that is often hidden from us. We often perceive people and situations inaccurately because of our own experiences or preconceived notions. This applies to our perceptions of ourselves, the way we see others and how we perceive a situation or relationship. Two often-used phrases that are highly applicable to pyrite meaning are: "Looks can be deceiving" and "Don't judge a book by its cover." Pyrite looks like something it isn't and helps us see things more clearly.
