Types of Crystals

Crystals are defined as solid minerals, in which component ions, atoms, and molecules are arranged in a regular structure. It is this orderly arrangement of the constituent particles that gives all types of crystals a straight edge and flat surface. Examples of common crystals include salt, sugar, snowflakes, gemstones, rubies and diamonds. Each of the crystal types possess a specific shape and different properties, based on which they are classified.

There are seven crystal systems or groups, each of which have a distinct atomic lattice. The atomic lattice is a three-dimensional network of atoms that are arranged in a symmetrical pattern. The shape of the lattice determines not only which crystal system the stone belongs to, but all of its physical properties and appearance. In some crystal healing practices, the axial symmetry of a crystal is believed to directly influence its metaphysical properties.

With the increased popularity of crystal healing, rigorous studies have been done on crystals and their meanings.
