The crystal is composed of three elements: crystal face, crystal edge and apex angle. It has a polyhedral shape and is a geometric body occupying three spaces. The three or four imaginary straight lines that meet in the center of the crystal are called the crystal axis of the crystal. According to the length of the crystal axis, the angle of intersection between each other and the inherent symmetry of the crystal itself, the crystal is divided into six major crystal systems.

① Equiaxed crystal system refers to a crystal system with three crystal axes of equal length and intersecting at right angles to each other at 90 degrees. Its crystal shape is octahedron, cube or rhombus dodecahedron. The gems belonging to this crystal system include diamonds, garnets, spinels, pyrites, vesaire.

②Tetragonal crystal system refers to a crystal system in which two crystal axes of the three crystal axes are of equal length and intersect at right angles with the third crystal axis of unequal length. Its crystal shape is a tetragonal column with a cross section square. The gemstones belonging to this crystal system include zircon, scleros and so on.

③ Hexagonal and trigonal crystal systems, the crystal system has four imaginary crystal axes, of which three crystal axes of equal length intersect at an angle of 60 degrees (trigonal) veya 120 degrees on the same plane, and are not upright with the fourth one. A crystal system with equal-length crystal axes intersecting perpendicularly has the shape of a trigonal or hexagonal column with a triangular or hexagonal cross-section. The gems belonging to the hexagonal crystal system include beryl, safir, kristal, tourmaline and so on.

④The orthorhombic crystal system refers to the crystal system with three crystal axes of different lengths and perpendicular to each other. Its crystal shape is short columnar and columnar, and the cross section is rhombus. The gemstones belonging to this crystal system include chrysoberyl and olivine.

⑤ Monoclinic crystal system, refers to the three crystal axes of different lengths, two of which intersect vertically on the horizontal plane, and the third crystal axis intersects diagonally with the crystal system. The crystal shape is granular or short columnar. The gemstones of the crystal series include jade and nephrite.

⑥Triclinic crystal system refers to a crystal system in which three crystal axes have different lengths, and the three intersect obliquely with each other. The crystals are parallel and double-sided, yani, a thin plate. The gems belonging to this crystal system include plagioclase, turquoise and so on.

Özetle, understanding the concepts and common sense of what is crystal system, kristal, crystal shape, vesaire., has important guiding significance for people to understand gems and to identify and evaluate gems.
