This bracelet is made with quality beads, a 14k gold filled lobster clasp, wire, & extender that will resist most wear & tear, with the right care. I highly recommend measuring your wrist for the best fit. Take a measuring tape & measure wrist tightly around. Add 1/2 inch to your measurement & that is the size you should order. Each bracelet comes with extra links that extend 1/2 inch beyond the size you order. If you are buying as a gift, this chart is a good guideline.
