Mineral crystal faces of varying luster and geometric shapes.
Beneficial to euhedral crystal shapes would be the proper temperature and length of time spent in ideal conditions for crystal formation for the particular mineral. Ideal conditions would include: space available for mineral crystal growth and availability or supply of mineral rich solutions bearing mineral components.
The sparkle is the reflection of light off the mineral crystal faces or cleavage surfaces.
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.
The mineral that commonly forms 12-sided crystals is called dodecahedrite, which is a form of garnet. However, one of the most well-known minerals with a dodecahedral crystal habit is quartz, specifically in its dodecahedral variety known as dodecahedral quartz. These 12-sided crystals are characterized by their geometric symmetry and distinct faces.
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.

They accumulate in crystal faces.
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.
If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
The area of crystal growth usually takes place on the outermost layers of crystal faces.
A crystal mineral is a naturally occurring solid substance with a specific chemical composition and a highly ordered atomic structure, resulting in a symmetrical external shape with flat surfaces called crystal faces.
The sparkle in minerals is usually caused by their crystal structure and the way they interact with light. When light enters the crystal lattice of a mineral, it can be reflected and refracted, creating a sparkling effect due to the reflection and dispersion of light off the crystal faces. The presence of impurities or inclusions in the mineral can also contribute to its sparkle.
A variety of the mineral zircon. "Name refers to its curved crystal faces. From the Greek κνρτος, for bent." mindat.org
