What is Shimmer AB?

The Shimmer AB coating is a softer, more luminous version of the traditional Aurora Borealis finish. Developed by Preciosa® to emulate the discontinued Swarovski Shimmer effect, it enhances the base color with a dreamy, light-reactive glow—bringing dimension and elegance to your design without overwhelming the crystal’s hue.
