Crystal habit and structure Quartz belongs to the trigonal crystal system at room temperature, and to the hexagonal crystal system above 573 °C (846 K; 1,063 °F). The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end.

In mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals. The habit of a crystal is dependent on its crystallographic form and growth conditions, which generally creates irregularities due to limited space in the crystallizing medium (commonly in rocks). WebCrystal habit and cleavage distinguish hornblende from dark-colored pyroxenes. Is a common mineral occuring in both igneous and metamorphic rocks. It characteristically forms near other amphiboles due to the complete solid solution. End members include: edenite, pargasite, hastingsite and tschermakite.
