Crystals Facts

Crystals Facts
A solid figure that is made up of a repeating pattern of geometric shapes is known as a crystal. Crystals form when a liquid cools and hardens. During this crystallization process, molecules within the liquid pull together in a pattern. Some crystals, such as emeralds, form when magma cools very slowly.

Although crystals typically grow naturally, they are sometimes produced by scientists in a lab under controlled conditions.
Not only do crystals have sharp edges but they also consist of flat faces called facets.

Most solids only form one type of crystal but there are some that can produce multiple crystals forms.
Almost all crystals have some type of imperfection where the pattern of shapes is distorted.
