A pendant with intertwined circles
 6 cabochon stones 4mm (Labradorite, Mother of Pearl, and Amethyst)
 Glue
 3mm rings
 Stud earrings

To start, position the stones in the desired spots. Make sure to place them on areas wide enough to have a good hold under the stones.

Once the spots are selected, place a small dot of glue and then gently apply the cabochon. Do the same for the other stones and then wait for complete drying.

For a more dynamic look, don't seek symmetry. Place the stones differently on the 2 pendants. 

Then, open a 3mm ring and connect the pendant to the earring loop.

Close the ring properly.

And there you go! Beautiful creation!
