of the chain
 3mm and 4mm rings
 a mini pebble pendant
 a clasp 
 of the extension chain

To make this bracelet, start by cutting 2 pieces of chain to the size of your wrist.

Then connect the pebble to the chain with a 4mm ring.

To merge the 2 chains together, on one side place the clasp with a 3mm ring and on the other the extension chain (about 3cm) also with a 3mm ring.

And there it is! Beautiful creation!
