Crystals Rocks Minerals Understanding the Difference

 · A crystal is a solid that s made up of a microscopic highly ordered arrangement of atoms that form a repeating three dimensional pattern known as a crystal lattice. A typical crystal contains billions of atoms and the shape they form is known as the crystal structure whilst their formation and subsequent growth is called crystallization. The
