Vitrail? What is it? Well, it is a special coating that Swarovski uses on its beads that flash purple and blue. Absolutely PERFECT for this year's Pantone color of ultra purple. We have 18 of these lovely 6mm round Medium Vitrail beads and offer them per bead at 50 cents. Just imagine a cluster of 9 per earring and you will surely want all 18 of them!
