The AB effect, named for aurora borealis (the northern lights), is a term for crystal stones that have a highly iridescent surface. Created 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. Combining the versatility of a flat back and the sparkling brilliance of a chaton, the light round stone gives you the best of both worlds.
