Dirigible

"Dirigible" is a waaaay cooler word than "airship"...  This isn't an Airship, it's a Dirigible. No, you can't fly it, it's made of brass, brass & bronze & oh look, there's some copper chain... 
That's a brass corrugated bead, bead cap, bead cap, bead cap & a connector. All put together to form something that, in my humble opinion, is rather pleasing to look at. It's not a delicate little thing, this isn't your mummy's pearl necklace (........) it's a substantial hunk of brass goodness that measures 2 inches across.
