A rock containing three crystals of pyrite
In crystallography, the cubic crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.
There are three main types of these crystals:
- Primitive cubic
- Body-centered cubic
- Face-centered cubic
