Symmetry is one of the most fundamental concepts in crystallography. Every crystal possesses a specific arrangement of atoms that repeats in a regular pattern, giving rise to predictable symmetry. These symmetrical features are described by symmetry elements, which...

Cleavage is one of the most important physical properties used to identify minerals. It describes a mineral’s tendency to break along flat, smooth, parallel surfaces called cleavage planes. These planes form because atomic bonds are weaker in certain directions...

Crystal habit describes the external shape or appearance that a mineral crystal develops during growth. Although a mineral’s internal atomic arrangement determines its crystal structure, environmental conditions such as available space, temperature, pressure,...

Crystals form in a wide variety of geological environments, each providing the conditions necessary for atoms to organize into ordered crystal structures. These crystal growth environments differ in temperature, pressure, fluid chemistry, cooling rate, and available...

Crystals are one of nature’s most remarkable creations. Every crystal begins as tiny atoms, ions, or molecules that gradually organize into a highly ordered and repeating three-dimensional pattern known as a crystal lattice. Over time, these microscopic building...
