A branch pendant
 Un incentive like 4mm
 From the chain
 Oval rings
 A clasp
 The extension chain

To begin, cut 2 pieces of chain, each about 18cm long, to make a choker necklace. Adjust the length to your taste.

Then open an oval ring and connect a piece of chain to the pendant. Do the same with the other chain.

In the centre of the pendant you will see an open ring which will allow you to connect the setting directly without the need for an additional ring. 

Finally, at the ends of the chains, place the karabiner on one side and the extension chain on the other.

And there you have it! Beautiful creation!
