What Is AB?
AB rhinestones feature an Aurora Borealis-style coating that creates a bold, rainbow-like flash over the base Crystal shade. As the light moves, the finish reflects multiple colors, adding extra sparkle, movement, and dimension to your design. AB stones are perfect for dance costumes, cheer uniforms, stagewear, tumblers, accessories, and projects that need high-impact shine.
