To begin, cut a chain to the length of your choice.
50cm for a short necklace or 75cm / 80cm for a long necklace.

Choose your pebble then open a 6mm ring. Insert the pebble pendant, then the decorative pendant and close the ring.

Pass the chain through the 6mm ring...

Finally, if you have made a long necklace, simply close the chain with a 3mm ring.

For a shorter necklace, use a lobster clasp and an extension chain with 3mm rings.

Et voilà! Beautiful creations!
