Each adjustable crystal bracelet features a beautiful one-of-a-kind gemstone. These adjustable bracelets are so easy to put on and fit everyone! Simply slide the largest bead down to slip on the bracelet then tighten the bead to your wrist for a custom fit. The rubber gasket inside the bead holds the perfect tension on the chain to keep it in place. The bracelet bands and components are nickel free, tarnish resistant 18k gold plated over brass. The bracelet will look gorgeous for years to come! To preserve the long life of your jewelry, remove it before showering, swimming, or working out. Because I use natural gemstones, the stones vary slightly in shape, shade and size. They also contain natural inclusions - each one is perfectly unique!
