Mineral crystal systems
WebCrystal Systems There are six crystal systems. All minerals form crystals in one of these six systems. Although you may have seen more than six shapes of crystals, they’re all variations of one of these six habits. Each system is defined by a combination of three factors: How many axes it has. The lengths of the axes. WebThe following table contains a selection of minerals gemologists may encounter as jewelry stones or gem specimens.
