What mineral that appears in transparent hexagonal crystals
The arrangement of atoms in a mineral sample can cause the formation of crystals.
The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
Gemstones are made from mineral crystals, yes.
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
a mineral
A mineral.
This mineral is called halite.
Sandstone typically does not have crystals. It is primarily composed of sand-sized mineral particles that are cemented together, giving it a granular appearance. If sandstone does contain crystals, they are usually very small and not easily visible to the naked eye.

. The growth of the crystals of one mineral on the crystal face of another mineral
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.
