Crystal (mineral)

A crystal is a solid material whose atoms are arranged in a highly ordered, repeating pattern, forming a geometric shape. Common examples include quartz, diamonds, and salt. Crystals are formed naturally through processes like cooling of molten rock or evaporation of water. They can be found in various colors and sizes and have unique properties such as clarity and hardness. Crystals are often appreciated for their beauty in jewelry and decoration, and they also hold significance in several cultures for healing and energy purposes. In science, they play a crucial role in fields like geology and chemistry.
