Black Obsidian moon and sterling neckwire or chain

Black Sheen obsidian Moon set in Sterling silver with a little aurora borealis vintage crystal on top.
The crystal and Moon are not being cooperative in the photo session.
This looks way better in person. The crystal is vibrant and has a beautiful rainbow flash. 
The hammered sterling neckwire is about 18-19 inches . Other choice is sterling neckchain (see pic) adjustable 16-22 .You can remove the pendant .
