- 1
Every crystal's atoms are arranged in a highly organized, repeating pattern, which is the defining feature of a crystal.
- 2
Each crystalline material’s atomic arrangement falls into one of six different families: cubic, tetragonal, orthorhombic, monoclinic, triclinic, and hexagonal.
- 3
Environmental conditions like pressure, temperature, and chemical environment can influence which geometric shape a crystal grows into.
