Crystal faces.
Symmetrical crystal shapes indicate that the mineral has a well-defined crystal structure with uniform internal arrangement of atoms or molecules. This suggests that the mineral formed under conditions that allowed for ordered growth, resulting in distinct geometric shapes.
Emerald is a variety of the mineral beryl, which is a silicate mineral. Silicate minerals are composed of silicon atoms surrounded by oxygen atoms. Therefore, emerald can be classified as a silicate mineral due to its composition.

Cleavage is the mineral property that depends on bond type and the spacing of atoms within the crystal. Cleavage is the tendency of a mineral to break along specific planes of weakness due to the arrangement of atoms and the type of chemical bonds holding them together.
Fracture
They accumulate in crystal faces.
Atoms accumulate on the surface of pre-existing mineral crystals or other solid surfaces during mineral growth. This process involves the deposition of ions and molecules from a solution onto the surface, leading to the formation of new mineral layers.
In and along the crystal planes.

new mineral with a different crystalline structure.
Arrangement of atoms and ions within the mineral's crystal lattice structure, which is determined by the mineral's chemical composition and bonding properties. This unique arrangement leads to the formation of distinct crystal shapes that can vary depending on external factors like temperature and pressure during the mineral's formation.
When liquid evaporates, atoms of dissolved minerals are left behind and form crystals. This process is known as crystallization. Over time, these crystals can accumulate and form mineral deposits.
The definition of mineral atoms are as follows: The grouping of individual atoms. These atoms have electrical charges, but only by gaining electrons.
The shape of the crystals in a mineral sample demonstrates the mineral's internal atomic arrangement and growth conditions. Different crystal shapes, such as cubic, hexagonal, or prismatic, indicate how the mineral's atoms are organized and bonded. This crystallographic property is called the mineral's crystal habit.
The number of atoms in a mineral varies depending on the type of mineral and its chemical composition. Typically, minerals are composed of repeating units called unit cells that contain multiple atoms. The number of atoms in a mineral can be determined by its chemical formula and the arrangement of atoms within its crystal lattice.
