Crystal Formations and Their Meanings

Crystal formations are the different shapes and sizes that crystals can grow in. The formation of a crystal depends on a number of factors, including the type of mineral, the temperature and pressure conditions under which it formed, and the presence of impurities.

Crystals are the outer form of a mineral's inner order. Nearly every piece of rock of Earth is made of minerals, each of which is defined as a natural substance with a precise recipe and arrangement of atoms.

Crystal Point: A single terminated crystal which can have many of the other features below. Crystal points are the most basic crystal formation. They have a single point at one end and a wider base at the other end.

Double Terminated: Double-terminated crystals have two points, one at each end.
