For chain maille, particularly jewelry made with fine jump rings like these, the jump rings need to be closed under tension. To do this use 2 flat-nose pliers and gripping both sides of the ring push the ends of the ring a little further than closed so the ends overlap, then bring the ends back to meet. There is usually a little clicking sound when they go from overlapped to meet perfectly. Check by feel or use magnification. If your rings aren't right keep adjusting and overlapping till you get a perfect ring.

Place 4 closed large rings on a small ring and close the ring. Add another small ring in the same place as the first small ring.

Take an open small ring and go through 2 of the 4 large rings, add 2 closed large rings and close the small ring. Add another small ring in the same place.

Join both ends of the chain together with a small ring. Add a second small ring in the same place. You now have a square looking chain shape.

Now we add 4 decorative rings, these rings don't go through any rings. They sit between the 2 large rings and go around the 2 small rings to create the pattern. The first ring will go around the 2 small rings at the bottom of the square. Take an open large ring, if you open it a little more than you usually do it will make it easier to manipulate. To make it easy to see I have marked this ring with a red dot. Starting at the bottom of the square, weave the ring up between the 2 large rings on the left of the bottom 2 small rings. Take this ring around the 2 small rings and down between the 2 large rings on the right. Close the ring.

To add the 2nd decorative ring move on to the next 2 small rings. Take an open large ring, weave this ring up between the 2 large rings on the left of the small rings, around the top of the small rings and down between the 2 large rings on the right. Close the ring.

To add the crystal cut a piece of wire about 1.2" (3cm) long. Place the edge of your flat-nose pliers about 2mm from the end of the wire and turn it back on itself to form a hook shape. With your pliers flatten the hook so the 2 sides are next to each other. Place a crystal bicone on the wire and with your round-nose pliers make a wrapped loop.

Take your chain maille shape and position one of the small 2 ringed links at the top. Attach the wrapped loop of the crystal drop to both of these small rings.

To make the ear wire I find it easiest to make both ear wires at the same time, so doing each step for both rather than making one then trying to make the second look the same. For each ear wire cut a piece of wire about 3.15" (8cm) long. Mark the middle of the wire. Hold the middle mark on your mandrel and bend the wire to the shape of the circle. It will spring back a little and end up a bit larger than the mandrel shape.

Place the side edge of your flat-nose pliers next to the middle mark, bend both sides of the half circle towards each other to make the ear wire shape. On one of the ends, with round-nose pliers make a loop that curves away from the main shape. If you like you can put a slight bend in the other end. The ear wires need to be work hardened so they maintain their shape. You can do this by hammering them with a rawhide or plastic mallet, or put them in a jewelry tumbler.
