2 small natural stone pebble pendants
 2 cabochons round 6 mm
 2 connectors for 6mm cab
 2 rings 4mm
 a pair of BO
 uhu glue

To begin, stick your 6mm stones into the appropriate connector brackets.

Wait for it to dry completely, preferably overnight.

Then connect the pebble pendant to the bottom of the connector using a 4mm ring.

On the top of the connector, connect the BO bracket by slightly opening the ring at the bottom of the bracket.

And voilà! Beautiful creation!
