Made to order by me in my Chatham, MA glass studio. The earrings are finished with Swarovski Crystals and sterling silver. This pair was made with transparent Cobalt Blue. At checkout you will have the choice of purchasing these earrings in their original shiny form or etched. The last pic shows what they will look like after being etched. Earrings always come with a back stoppers to minimize risk of loss while wearing. All beads are properly annealed to assure strength and durability.
