What Are Crystals?
Before we dive into the world of geology and crystallography, it’s essential to understand what crystals are. Crystals are solid materials whose atoms, molecules, or ions are arranged in a repeating pattern, called a crystal lattice. This repeating pattern gives crystals their unique properties, such as their shape, symmetry, and optical characteristics.
Crystals can be found naturally in the earth’s crust, and they come in a wide range of shapes, sizes, and compositions. From the majestic quartz crystals that adorn the walls of caves to the tiny crystals that make up the rocks that we walk on, crystals are an integral part of our planet’s geology.
