Swarovski's AB effect, named for aurora borealis (the northern lights), is a term for crystal stones that have a highly iridescent surface. Created by Swarovski in 1955 in collaboration with Christian Dior, the effect is achieved by vapor blasting the facets of the lower part of the crystals with an invisible, micro-thin metal sheet.
Sparkling seaside fun! Swarovski crystal starfish drop is precision-beveled and faceted to enhance the color and flash of the superior-quality crystal.
