Swarovski Crystal -Article 5107 Pagoda (Potato Chip)
This shape is highly collectible, it was only made for a few years, so it's one of the rarest Swarovski beads. It has vertical facets on one side and horizontal on the other.
It creates a checkerboard effect. One side has a silvery AB coating.
The Rights are drilled on the AB (bottom) side and the Lefts are drilled on the top. If you use all rights or lefts they will be
strung as in the picture below. If you alternate lefts and rights they
will interlock with only the top showing or only the AB side showing.
