It will give a good idea of how to go about creating most of the elements that went into this earring and allow you to create a similar pair.
For these earrings you will need:
Copper wire and Green craft wire in 20 gauge
2 seed beads
8 silver-lined cube beads
4 jump rings large enough to put the cube beads on (I made mine with pliers)
6 equal lengths of chain (I used bar chain by the foot bought online at Beadaholique)
You will only "need" pliers to bend the wire, cutters for the wire, a file, and hammer/anvil for tools... but a Wig Jig is certainly useful. And a rubber mallet can be nice so you don't risk marring the wire when you are just hardening it.
Step 1: Make the Connectors
If you have a wire jig, put the pegs in as shown and make two.
If you aren't so lucky, carefully bend with pliers until you get a similar shape. And then do another as close as possible. You could also make an improvised wire jig with a board and some nails.
Use your anvil/flat surface and mallet or hammer to harden the connector shape and make it nice and flat.
