Our Anklets are created using Swarovski Crystals and Sterling Silver. We have them premade to fit a small ankle (8 1/2″ – 9 1/2″) and a medium ankle (10″ – 11″). They come with a 1 1/2″ extension and a lobster clasp. They are very strong – test driven by a very active 17 year old granddaughter. We can also custom make them to fit any size ankle.
