Amethyst is the violet variety of quartz; its chemical formula is SiO2.
The crystaline form is rhombohedral
The rhombohedral system can be thought of as the cubic system stretched along a body diagonal. a = b = c; α = β = γ ≠90°.
There are six sides to a pure simple crystal.
Cubic close packing results in cubic crystals. See the picture in the Wikipedia page (link found to the left of this answer). The answer is then: 6 sides.
Salt crystals are cubic. They should appear as interconnected cubes.
If a mineral belongs to the hexagonal crystal group, then the crystals have six sides.
A hexagon will tessellate a plane so a hexagonal crystal is likely to be a hexagonal prism. In that case, it will have 8 faces.
Quartz had six sides.
A sugar crystal has 12 sides.

hexagonal crystal system ( 6 sided )
The crystalline structure of titanium is hexagonal.
If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
The number of sides a crystal has depends what minerals or elements make up the crystal. A cubic crystal has 6 sides. A hexagonal crystal with flat ends has 8. A hexagonal crystal with pointed ends has 18.
It has eight sides.
Graphite is an example of a hexagonal crystal. Beryl also forms a six sided crystal.Magnesium exhibits close packed hexagonal crystal structure.
A hexagonal prism is a prism composed of two hexagonal bases and six rectangular sides.

You can say how many sides does a hexagonal shape have?
exactly 6 sides
A hexagon has six sides.
It will have 8 sides.
A hexagonal prism has 8 sides, 12 vertices, and 18 edges.
It has 8
