When you hear someone referring to an “AB” finish on their beads, they’re talking about an “aurora borealis” coating. It’s a treatment that gives glints of many colors over what would otherwise be clear glass. I think it might have originated with Swarovski but by now, most reputable manufacturers have their own version.
