Mandala Stamped Rustic Brass Armor Necklace

This rustic, bohemian necklace is made from a large (2 3/4" wide) brass plate that I've stamped by hand with repeating, symmetrical pattern that resembles a mandala. 
Each design is one-of-a-kind and will differ slightly from the photos.
It hangs from an 18" brass roll chain, finished with a lobster clasp closure.
