How Crystals Form
Ever wonder how crystals form? Let’s take an imaginary journey to the center of the earth and find out!
Different types of crystals are created in different ways, but almost all crystals form by new matter being added to a mass of crystal that’s already growing.
Some, such as quartz minerals, begin their life in the fiery gasses found in the center of the earth (magma) or in volcanic lava that’s streamed up to the earth’s surface.
As it cools and hardens these magmatic, or igneous, crystals are formed. This can happen quite quickly, resulting in small crystals, or take eons, allowing large crystals to form. (more…)
