I made this steampunk necklace. The gears, cogs, machine screw, nut, and chain are made out of copper, bronze, steel, and brass. The main round part with little hobnails on it is bronze plated pewter. The little gears and cogs in the middle actually turn, which I think is pretty cool. I was inspired to make this necklace after reading about Tess McKinett’s necklace in my father’s newest steampunk manuscript. Then I made matching copper earrings to go with it.
