AB is aurora Borealis
the Northern Lights, which are crystals that have been given an iridescent coating that shimmers when it catches the light.
The difference with a normal clear crystal is the finish has been added to the bead to add extra colours to the different facets or cuts to the bead.
This creates the more dreamy, unique mood
We have 2 different types of AB crystal, coated on top of zirconia or jelly crystal. (jelly crystal is kind of water jelly look of crystal)
