A little bit medieval, a little bit steampunk... This necklace is a "circle of life" knot made of brown leather cord studded with copper beads.
It hangs on an adjustable brown leather cord-- the silver fittings slide to allow the necklace over your head, then you can pull them to adjust the pendant to hand where you want, either as a choker or lower.
The knot is just over an inch in diameter, and the entire pendant is about 2 inches long.
The fittings are custom made of copper wire. The beads are copper.
