Crystal faces are the flat surfaces that form on the outside of a crystal during growth. These surfaces develop in response to the crystal’s internal atomic structure and are one of the most important features used in mineral identification. Well-developed...

The Trigonal Crystal System is one of the seven crystal systems used in mineralogy and crystallography. It is closely related to the hexagonal crystal system but differs because it has three-fold rotational symmetry instead of six-fold symmetry. Many important...
