Pyrite crystals typically form in the shape of cubes or pyritohedrons, which are 12-sided geometric shapes with pentagon and hexagon faces. These crystals can also show striations and faces with a metallic luster.
Mineral crystal faces of varying luster and geometric shapes.
Rose quartz and smoky quartz are considered crystaline minerals due to their internal atomic arrangement, but they do not exhibit visible crystal faces because they often form in massive or granular structures rather than distinct crystal shapes. This lack of well-defined crystal faces is due to the specific conditions under which these minerals are formed in nature.
Parallel lines seen on crystal faces or cleavage planes are called growth striations. They are caused by variations in the crystal's growth rate or conditions during formation, resulting in alternating layers of different densities or compositions. These striations can provide valuable information about the crystal's growth history and conditions.
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
Crystal Systems is the word for "observe number and angle of crystal faces."
The angle between equivalent faces of crystals of the same substance is known as the interfacial angle. This angle is characteristic of the particular crystal system and reflects the symmetry and arrangement of atoms within the crystal lattice. It remains consistent for a given substance regardless of the size or shape of the crystal. This property is crucial in identifying and classifying minerals and other crystalline materials.
I believe the answer would be the crystal system, but the crystal system is based on the angles and length of the axis of the crystal. The axis length and the angle at which they meet would affact the number and angle of the crystal faces.
sorry i do not know
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.

The angle at which crystal faces meet, known as the interfacial angle, is crucial because it reflects the internal symmetry and arrangement of atoms within the crystal lattice. This angle influences the crystal's overall shape and growth habits, which can affect its physical and chemical properties. Additionally, understanding these angles can aid in the identification of minerals and their classification in geological studies.
Quartz vibrates when a voltage is applied between opposite faces of a crystal. The frequency of the vibration depends on the thickness of the crystal, and on the direction of the faces compared to the natural planes in the crystal structure.
