This unique bangle is made of _'' thick copper. It was hammered to achieve the textured finish. The bow design is made of silver that was reticulated. This bracelet has a 2 1/2'' diameter. Take note that the bangle will develop patina as you wear it. This is because the copper does not have a coating or wax, as I wanted to preserve its healthy benefits for the wearer. Please let me know if you want it to be varnished.
