Stunning colour! Vintage Swarovski beads. Silver foiled on one side. Left orientation = hole drilled on back (foiled) side. Also known as potato chip beads - these are no longer in production, as they were too expensive to make. The left and right versions of these are designed to overlap when strung alternately (originally - they were designed to sew onto clothing). Alternate Left and Right for the full overlap effect.
10mm x 10mm By the each.
