Aurora Borealis (or AB for short) is a name given to a glass or crystal bead that has been treated with a metalic finish, rendering an iridescent play of colors.
First developed in the 1950s by Swarovski, AB is a reliable indicator for dating costume jewelry. Bottom line: if the piece contains AB - and you believe the AB to be original to the piece - it can't be accurately attributed as dating to a pre-1950s era.
Happy Hunting,
