These czech hand made beads are made individually from lampwork glass. Each bead is a work of art , as artisans mix the molten glass colors to create an inlay. This stunning bracelet is made using 2mm silver mini beads, silver bead cap, 4mm coral swarovski simulated pearl and 6mm bead. All components are sterling silver. Worried about your child's growth? We thought of that too. We included sterling silver extenders to adjust as your kid grows. The pearls are strung on 49 strands of jewelry wire, which is very strong. We have a picture frame weighing 70 Lbs and we use this wire. It's still up 4 years and counting. Each end is triple-secured to guarantee quality and safety. Our team of professionals secure and check each bracelet by hand for durability, safety and quality.
