How are cubic pyrite crystals formed?
Cubed pyrite crystals are formed through a process called cubic crystal growth. This process occurs when the mineral is in a liquid or aqueous solution and is in a state of supersaturation. This means that the solution contains more of the mineral than it can hold in solution, and the excess begins to precipitate out as crystals.
