This is one of the first steampunk items that I’ve actually made, back in July, when I’ve got my first shipment of watch parts. I sort of forgot about it and listed it on Etsy just recently.
I have no idea what the stone is – could be obsidian or a dyed rock for all I know. It came in a mix of donut beads.
The name comes from the fact that the pendant resembles a wall clock a little bit, with the chain and the bead on the end of it as a pendulum.
