- Asterism — A remarkable optical phenomenon found in certain crystals and gemstones (such as star sapphires or star rubies), manifested by a star-shaped light reflection with multiple rays, caused by light refraction on geometrically oriented micro-inclusions; in astronomy, it denotes a small group of stars forming a recognized geometric figure in the night sky that is not an official constellation; in typography, it represents a group of three asterisks (⁂) used to separate text sections.
