Fast Facts
- Crystal comes from the Greek word “krystallos”, or ice.
- Crystals are not alive but they appear to grow as more atoms connect and form.
- The Cave of Crystals, or Cueva de los Cristales, in Chihuahua, Mexico contains the largest natural crystals ever found.
- Sometimes crystals grow in hollow spaces inside rocks, forming beautiful crystal-lined pockets called geodes.
Crystals are special kinds of solids where the tiny particles inside, called atoms or molecules, are arranged in repeating patterns. Because of this orderly structure, crystals often grow into beautiful shapes with flat sides and sharp edges. You can find crystals in nature in rocks and minerals such as quartz, salt, and even snowflakes. Some crystals are clear, while others are colorful and shiny.
Crystals form when liquids cool or when water evaporates and leaves tiny particles behind that slowly lock together in a pattern. This process can take a long time in nature—sometimes hundreds or even thousands of years! Deep inside the Earth, heat and pressure help many crystals grow.
People use crystals in many everyday things. For example, quartz crystals help keep time in watches and clocks. Salt crystals are used to flavor food, and some crystals are used in electronics.
Besides being useful, crystals are also admired for their beauty and are often made into jewelry and decorations. Gems are mineral crystals that have been cut and polished, and are often selected for their brilliant color.
