I made this necklace by soldering together open hoops from an old project that ended up not happening.
Once soldered I put the pieces through my patterned rolling mill and attach them to each other and the chain with copper hoops. Everything is given the raw, antigued finish by being oxidized and then brushed.
The middle piece measures 30x30mm, the two pieces on each side 25x25mm, the chain is 150mm oneach side and the handmade s-lock lock measures 25mm.
