What is a crystal?

Where do crystals come from and how is a crystal created?
Crystals form deep in the earth's interior and it often takes a very long time for a crystal to form, sometimes thousands or millions of years. Liquid magma moves inside the earth's core and when magma for various reasons moves up towards the earth's surface it cools and different crystals can then form depending on how quickly the temperature drops.

Where do you find crystals?

What is the difference between precious stones and semi-precious stones?
