What is Shimmer AB?

The Shimmer AB finish is a refined take on the classic Aurora Borealis coating. It enhances the rhinestone’s color without overpowering it, creating an airy, luminous quality that reflects light beautifully from every angle. Comparable to Swarovski’s “Shimmer” effect, this Preciosa version offers a sophisticated touch of iridescence.
