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.
Much like its counterpart (the faceted column pendant), the Swarovski column bead with two holes boasts a faceted slender surface, though the facets in this style are asymmetrical on both sides. Named for its double-drilled sides, the column bead with two holes lends itself ideally as a sparkling spacer bead in designs. Designer note: the AB effect is always applied to one side, which can be either side of the crystal component.
