For the mother-of-pearl bracelet:

To start, cut a faceted oval link chain to your wrist size minus 1.5cm (corresponding to the clasp + adjustment chain).

Thread the mother-of-pearl beads onto flat head pins.

Attach the beads centered on the chain. 

Cut about 3cm of extension chain. Then connect the clasp on one side with a 3mm ring and the chain on the other side with a 3mm ring.

For the rosary chain bracelet:

Measure your wrist. Subtract the value of the connector and 1.5cm. Divide the value by 2 then cut 2 pieces of rosary chain.

Connect the chain pieces to the connector with 3mm rings.

To finish, connect the clasp and the extension chain with 3mm rings. 

And there you go! Beautiful creation!
