The shapes are called crystals.

Crystals
The arrangement of atoms in a mineral sample can cause the formation of crystals.
most minerals have a distinctive crystal arrangement. those minerals that do not have their atoms arranged in crystals are called amorphous minerals.
A crystal has an orderly repeating pattern of atoms, so does a polymer. The term "polymer" is usually reserved to describe a substance with a repeating pattern of formula units (monomers) which are groups of atoms.
called crystals. This arrangement creates the orderly structure typical of solid crystalline substances. The repeating pattern of atoms gives crystals their unique properties, such as symmetry, cleavage, and optical effects.
Atoms are bonded in ionic crystals.
Graphite crystals have a hexagonal shape due to the arrangement of carbon atoms in layers called graphene sheets. These sheets are stacked on top of each other, forming the distinct hexagonal shape of graphite crystals.
Crystals
It's called crystalline structure.
