What Is AB?
AB stands for aurora borealis, a coating applied to select crystals that creates a soft, shifting rainbow iridescence across each facet. Crystal AB is available in standard, uncoated Crystal and also available coated with the aurora borealis (AB) effect, which is what brings the color play to an otherwise clear stone.
