This fashion genuine stone beads bracelet is weaved together using genuine chip beads (unless stated otherwise) with antiqued silver-plated (darker silver) toggle clasp finishing off the bracelet.  If you are handy at jewelry making you could always take off the clasp to add your own sterling silver one & additional jump rings should you want more length.  
.
The nugget/chip beads weaved together will take up wrist space so this will actually fit at a smaller wrist size depending on if you like to wear your bracelet tight or loose ... maybe ~0.25-0.50" less.  There is ~1-1/2" extender chain should you need more length option.  This makes a perfect gift for that special someone even if that is you.  Photo is ENLARGED to show detail.

There are plenty of free online measurement converters should you want different measurements.
