Obsidian Wire Wrapped Pendant in Oxidized Copper

The stone is Obsidian(in sunlight it looks purple, otherwise it looks black). 

The wire is solid copper that has been oxidized. A cord necklace is included, it is nylon and is adjustable roughly 18"-20". Please note that copper naturally darkens with age and if necessary may be cleaned to lighten it back up, a polishing pad is included with your order.  The last photo shows back of the pendant, it is next to a ruler for size comparison.
