Found in nearly every colour – most notably red, pink and blue – spinels are popular gemstones because of their abundance, moderate cost and attractiveness. Red spinel has often been mistaken for ruby. Some spinel exhibits asterism (a star-shaped pattern of reflections), chatoyancy (a “cat’s-eye” effect seen in reflected light) or a colour change when viewed alternately under incandescent and fluorescent lighting.
