WebFor gemologists, the scientific definition of a crystal goes right to the atomic level. A crystal is a solid whose atoms are arranged in a "highly ordered" repeating pattern. These patterns are called crystal systems. If … WebThe scientific definition of a crystal is based on its internal structure rather than its outward appearance. All matter on Earth is made up of atoms or, more frequently, combinations of atoms called molecules. If the molecules of a substance are arranged in a regular repeating pattern, the substance is a crystal.
