This one-of-a-kind necklace is all handcrafted. I used copper and brass sheet metal along with copper wire and copper tube. To get the sheet metal to the right shapes, I used a hand saw known as a jeweler saw. I wanted to add some kind of wood to the piece so I made a wood frame around the center gear work. The wood is held in with 4 brass corner caps that are screwed down using 4 handmade copper nuts. As for the rest of the metal work, I used easy, med, and hard silver solder.
