Crystals are all around you! They are pieces of matter where the molecules fit together in a pattern. This creates many different shapes and patterns. A few common types are amethyst, quartz, and even salt! When you think of them, do you think of jewelry? I know I do! Let’s learn about these beautiful rocks and how they are formed.

Types of Crystals
- Calcite – Calcite is usually white, grey, yellow, or green. They are made out of limestone and marble and are one of the most useful crystals in the world. We use it in construction, water treatment, medicine, and even chalk!
- Celestine – Celestine gets its name from its beautiful blue color. It is widely used for fireworks, healing, and in metal.
- Citrine – Citrine is a very bright yellow crystal. It gets its name from the French word “Citron”, or Lemon. Citrine is a gemstone. Like most, we don’t use it for much besides its appearance. But, it is November’s birthstone!
- Corundum – Ruby and Sapphire are two types of Corundum. They are all the same thing, but they have different colors. They can be red, blue, green, or even purple! We use it today to make sandpaper and polish metal!
- Fluorite – Fluorite is a colorless, brittle crystal. The name comes from the Greek word fluere, meaning to flow. We use it in decorations and glass today. Did you know that Fluorite glows blue under a black light? Cool, right?
