In gemology, aventurescence (sometimes called aventurization) is an optical reflectance effect seen in certain gems. The effect amounts to a metallic glitter, arising from minute, preferentially oriented mineral platelets within the material. These platelets are so numerous that they also influence the material's body colour. In aventurine quartz (actually a type of quartzite) chrome-bearing fuchsite makes for a green stone, and various iron oxides make for a red stone.
