This focal construction in pure copper just need few elements to be a finished piece, depending of the style you want to create. After bending softy to the desired position around the neck -it ships flat- chain and a clasp will give the last touch since it has been even lightly polished keeping the fire patina as much as it was possible. 
If you want a bolder design, a cascade can be added using toe loop on the front -otherwise just decorative- with bone, old beads, dangles, whatever your muses whisper when is on your hands.
It measures -flat- approx. side to side approx. 6 inches.
