6 Cowrie pendants
 5mm rings
 7mm cabochons
 Earring settings for 7mm cabochons
 Some glue

To start, open a 5mm ring then insert 2 cowrie pendants. Be careful to position them in the same direction. Then properly close the ring.

Continue the cascade, open a 5mm ring then attach a new cowrie to the previous cowrie.

 For a harmonious look, make sure to place all the cowrie pendants in the same direction.

Then, do the same for the 2nd earring, assembling the other 3 cowries in cascade.

Now, place a small drop of glue in the earring setting. Be careful not to use too much; place the drop of glue right in the center of the setting. Once the stone is in place, the glue will spread. 

If you applied too much glue, you can remove it with a small point like a toothpick. It's better to remove it beforehand to prevent overflow on the setting and the stone.

Place the cabochon in the setting then wait a few minutes before handling the earring.

To finish, gently open the ring on the earring base then attach the cascade of cowries.

And there you go! Beautiful creation!
