crystal
[noun]
A solid of defined shape that is bound by plane surfaces (facets) that intersect at characteristic angles. The shape of a crystal is defined by the bonding and/or interaction between atoms, ions, or molecules that make up the solid. The substances, planar angles, and defects in a crystal affect the electrical and optical properties (including color) of the crystal.
