Some Swarovski crystal beads have an AB coating or an AB2X coating. AB stands for Aurora Borealis like the Northern Lights. The AB coating on a bead gives it an extra sparkle and rainbow shimmer. AB2X coating is even more sparkly with the AB coating applied all over the bead rather than just on half of the facets. This effect was created in 1956 during a collaboration with Christian Dior.
Another finish that has been applied to some crystals is the Shimmer finish, this is similar to the AB effect but it leaves a softer rainbow sparkle which radiates 3 colours across the facets.
Swarovski have been creating sparkling crystal beads since 1895 and are used in lots of jewellery making designs, they are especially popular for bridal jewellery.
