Chapter 1
What are crystals?
Rounded Rectangle
Crystals are colorful things that form in the earth. They come in many shapes and sizes. Crystals are used for many things. For example, graphite is a crystal used in pencils. This allows us to write with them.

Some crystals have more value than other crystals. For example, diamonds are less common to find than salt. This is because there are only a limited amount of diamonds in the Earth. Salt is more common because it is still forming today.
Diamonds are very rare crystals. About 1 karat of diamond is worth $3,200!

How do crystals form?
Rounded Rectangle
Most crystals (like quartz) form from atoms. Atoms combine in 3D shapes and depending on the shape and type of atoms, a crystal is made.

There are many ways crystals form. Diamonds form in special tubes called kimberlite tubes. They are tube-shaped rocks that grow diamonds in them and then push them to the surface of the Earth. Amethyst crystals form on melted rocks and lava. Salt forms by water eroding rocks. The water dissolves some of the rock's elements like potassium, and then salt is formed!
This photo shows how the formation of atoms turn into crystals.
