Crystal Forms 
and Aggregates

Pyrite can form in extremely well-crystallized examples of cubes, pyritohedrons, and octahedrons. Combinations of these forms also occur. An icosahedron formed from a combination of an octahedron and pyritohedron is also known. Pyrite crystals frequently form penetration twinning, especially in thecubic form. Cubes are sometimes elongated in rectangular form. Also occurs massive, radiating, grainy,flaky, drusy, mammilary, encrusting, nodular, tuberose, fibrous, in concretions, and as groups of small crystals. Pyrite crystals are frequently striated.
